常见.NET功能代码汇总

1,在Web上修改指定文件位置的Web.config

这里需要使用 WebConfigurationManager 类,但必须使用WebConfigurationFileMap类来指定文件位置,看代码:

long appId = 123; //修改网站的配置文件 var configFile = new FileInfo(configFilePath); var vdm = new VirtualDirectoryMapping(configFile.DirectoryName, true, configFile.Name); var wcfm = new WebConfigurationFileMap(); wcfm.VirtualDirectories.Add("/", vdm); var config = WebConfigurationManager.OpenMappedWebConfiguration(wcfm, "/", siteName); AppSettingsSection appSection = (AppSettingsSection)config.GetSection("appSettings"); appSection.Settings["abc"].Value = "system tag"; appSection.Settings["appId"].Value = appId.ToString(); config.Save();

 上面的代码参考自 stackoverflow ,但是OpenMappedWebConfiguration 必须指定第3个参数,否则会报错。不过,siteName 并不要求与IIS的站点名字对应,随意写一个也可以。

 2,使用angularJS 绑定站点信息

首先定义一个 webSiteListApp HTML代码片断:

<div ng-app="webSiteListApp" class="container">    <div ng-controller="webSiteListController">        <ul>            <li ng-repeat="item in siteList">                站点名:{{item.SiteName}} ------绑定信息:{{item.DomainPort}}            </li>        </ul>    </div></div>

然后定义module和service:

<script type="text/javascript">    // 参考 http://www.infragistics.com/community/blogs/dhananjay_kumar/archive/2015/05/13/how-to-use-angularjs-in-asp-net-mvc-and-entity-framework-4.aspx    var webSiteListApp = angular.module("webSiteListApp", []);    webSiteListApp.controller("webSiteListController", function ($scope, webSiteService) {        getSiteList();        function getSiteList() {            var list = webSiteService.getSiteList()            .success(function (sites) {                $scope.siteList = sites;                console.log($scope.siteList);            })            .error(function (error) {                $scope.status = 'Unable to load customer data: ' + error.message;                console.log($scope.status);            });                  }    });    webSiteListApp.factory("webSiteService", ["$http", function ($http) {        var webSiteService = {};        webSiteService.getSiteList = function () {            return $http.get("/SiteManage/GetServerBindings");        }        return webSiteService;    }]);</script>


这里定义了一个叫做 webSiteListApp 的module,然后注册一个 webSiteListController 的控制器,该控制器在前面的HTMl代码中定义,最后创建一个 webSiteService ,它监听后来MVC来的数据,该数据对应的ASP.NET MVC 方法如下:

        public JsonResult GetServerBindings()        {            var siteList = IISControlHelper.IISWorker.GetServerBindings();            return Json(siteList, JsonRequestBehavior.AllowGet);        }

3,IIS管理程序

可以创建,删除网站,添加应用程序池,代码如下:

using System;using System.Collections;using System.Collections.Generic;using System.DirectoryServices;using System.Linq;using System.Net;using System.Text;using System.Threading.Tasks;namespace IISControlHelper{    /// <summary>    /// IIS 操作方法集合    /// http://blog.csdn.net/ts1030746080/article/details/8741399 错误    /// </summary>    public class IISWorker    {        private static string HostName = "localhost";        /// <summary>        /// 获取本地IIS版本        /// </summary>        /// <returns></returns>        public static string GetIIsVersion()        {            try            {                DirectoryEntry entry = new DirectoryEntry("IIS://" + HostName + "/W3SVC/INFO");                string version = entry.Properties["MajorIISVersionNumber"].Value.ToString();                return version;            }            catch (Exception se)            {                //说明一点:IIS5.0中没有(int)entry.Properties["MajorIISVersionNumber"].Value;属性,将抛出异常 证明版本为 5.0                return string.Empty;            }        }        /// <summary>        /// 创建虚拟目录网站        /// </summary>        /// <param name="webSiteName">网站名称</param>        /// <param name="physicalPath">物理路径</param>        /// <param name="domainPort">站点+端口,如192.168.1.23:90</param>        /// <param name="isCreateAppPool">是否创建新的应用程序池</param>        /// <returns></returns>        public static int CreateWebSite(string webSiteName, string physicalPath, string domainPort,bool isCreateAppPool)        {            DirectoryEntry root = new DirectoryEntry("IIS://" + HostName + "/W3SVC");            // 为新WEB站点查找一个未使用的ID            int siteID = 1;            foreach (DirectoryEntry e in root.Children)            {                if (e.SchemaClassName == "IIsWebServer")                {                    int ID = Convert.ToInt32(e.Name);                    if (ID >= siteID) { siteID = ID + 1; }                }            }            // 创建WEB站点            DirectoryEntry site = (DirectoryEntry)root.Invoke("Create", "IIsWebServer", siteID);            site.Invoke("Put", "ServerComment", webSiteName);            site.Invoke("Put", "KeyType", "IIsWebServer");            site.Invoke("Put", "ServerBindings", domainPort );            site.Invoke("Put", "ServerState", 2);            site.Invoke("Put", "FrontPageWeb", 1);            site.Invoke("Put", "DefaultDoc", "Default.html");            // site.Invoke("Put", "SecureBindings", ":443:");            site.Invoke("Put", "ServerAutoStart", 1);            site.Invoke("Put", "ServerSize", 1);            site.Invoke("SetInfo");            // 创建应用程序虚拟目录            DirectoryEntry siteVDir = site.Children.Add("Root", "IISWebVirtualDir");            siteVDir.Properties["AppIsolated"][0] = 2;

           siteVDir.Properties["AppFriendlyName"][0] = "Root";            if (isCreateAppPool)            {                DirectoryEntry apppools = new DirectoryEntry("IIS://" + HostName + "/W3SVC/AppPools");                DirectoryEntry newpool = apppools.Children.Add(webSiteName, "IIsApplicationPool");                newpool.Properties["AppPoolIdentityType"][0] = "4"; //4                newpool.Properties["ManagedPipelineMode"][0] = "0";

View Code

然后,写一个页面来创建网站:

前端HTML:

 <form action="/SiteManage/CreateWebSite">        <fieldset>网站名称(不能重复):————<input type="text" name="siteName" class="myInput" />  </fieldset>        <fieldset>网站基准目录(服务器):———<input type="text" name="physicalPath" class="myInput" /></fieldset>        <fieldset>绑定域名(不能重复):————<input type="text" name="domain" class="myInput" /></fieldset>        <fieldset>网站压缩文件路径(服务器):—<input type="text" name="zipFile" class="myInput" value="@ViewBag.ZipFile" /> 如果服务器没有网站压缩文件,请先上传。</fieldset>        <input type="submit" name="submit1" value="提交" />    </form>

后端Controller:

 public ActionResult CreateWebSite(string siteName, string physicalPath, string domain, string zipFile)        {            bool hasErr = false;            string message = "";            string webSiteFolder = "";            //检查参数,physicalPath 允许不存在,之后解压缩文件的时候将自动创建            if (string.IsNullOrEmpty(siteName) ||                 string.IsNullOrEmpty(physicalPath) ||                 string.IsNullOrEmpty(domain) ||                 string.IsNullOrEmpty(zipFile))            {                hasErr = true;                message = "参数不能为空!";            }                        //检查是否已经包含了要绑定的域名,如果是,则不允许创建            if (!hasErr)            {                var list = IISControlHelper.IISWorker.GetServerBindings();                foreach (var item in list)                {                    if (string.Compare(item.DomainPort, domain, StringComparison.OrdinalIgnoreCase) > 0)                    {                        hasErr = true;                        message = domain + " 域名已经绑定过,不能创建绑定此域名的新站点。";                        break;                    }                }            }                        //检查网站目录并解压缩文件到网站目录            if (!hasErr)            {                try                {                    webSiteFolder = CheckWebSiteFolder(physicalPath, zipFile);                    if (System.IO.File.Exists(zipFile))                    {                        UnZipFile(zipFile, physicalPath);                    }                    else                    {                        message = zipFile+" 文件不存在!";                        hasErr = true;                    }                }                catch (Exception ex1)                {                    message = ex1.Message;                    hasErr = true;                }            }                        if (!hasErr)            {                try                {                                       //创建网站                    int siteNumber;                    siteNumber = IISControlHelper.IISWorker.CreateWebSite(siteName, webSiteFolder, "*:80:" + domain, true);                    message = siteNumber > 0 ? "成功" : "失败";                }                catch (System.Runtime.InteropServices.COMException exCom)                {                    hasErr = true;                    if (exCom.HResult == -2147024713)                    {                        message = "网站名已经存在!";//(应用程序池IIS进程)文件已经存在,上面的方法默认会创建跟网站同名的应用程序池名称                    }                    else                    {                        message = exCom.Message;                    }                }                catch (Exception ex2)                {                    hasErr = true;                    message = ex2.Message;                }                           }            ViewBag.SiteName = siteName;            ViewBag.PhysicalPath = webSiteFolder;            ViewBag.Domain = domain;            ViewBag.ResultDesc = message;            return View("CreateResult");        }

注意这里会创建一个跟站点名字同名的应用程序池,默认是.NET 4.0,创建后即启动站点。

4,ASP.NET MVC 上传文件

前端HTML:

    <form action="/SiteManage/Upload" method="post" enctype="multipart/form-data">        上传网站压缩文件:<input type="file" name="file1" value="" style="width:300px;" class="myInput" /> <input type="submit" name="submit2" value="上传" />        <span>@ViewBag.Message </span>    </form>

后端Controller:

public ActionResult Upload()        {            string message = "";            HttpPostedFileBase file = Request.Files["file1"];            if (System.IO.Path.GetExtension(file.FileName).ToLower() != ".zip")            {                message = "只能上传ZIP格式的压缩文件。";                return RedirectToAction("Index", new { zipFile = "", message });            }            else            {                string filePath = System.IO.Path.Combine(HttpContext.Server.MapPath("../Uploads"), System.IO.Path.GetFileName(file.FileName));                file.SaveAs(filePath);                message = "上传成功";                return RedirectToAction("Index", new { zipFile= filePath,message});            }        }


注意Request.Files["file1"] 表示获取前端HTML页面的文件双传控件名字 file1 对应的文件。

5,.NET解压缩文件

.NET 4.5之后,集成了文件解压缩功能,下面是使用方法:

 /// <summary>        /// 解压缩文件到指定目录,将在指定目录下解压出一个压缩文件名字的最终的目录        /// </summary>        /// <param name="ZipPath">ZIP文件路径</param>        /// <param name="ExtractPath">要解压缩的目录</param>        private void UnZipFile(string ZipPath,string ExtractPath)        {            //string NewFile = @"c:\users\exampleuser\NewFile.txt";            if (System.IO.File.Exists(ZipPath))            {                using (ZipArchive Archive = ZipFile.Open(ZipPath, ZipArchiveMode.Update))                {                    //Archive.CreateEntryFromFile(NewFile, "NewEntry.txt");                    //如果目录下面有文件,将解压缩失败,所以之前先备份目录                    Archive.ExtractToDirectory(ExtractPath);                }            }        }

注意这里支持ZIP格式,不是RAR格式,同时需要使用 using System.IO.Compression;相关的程序集。

6,备份文件夹

如果需要备份文件夹,可以使用Move 方法实现,看代码:

  /// <summary>        /// 检查站点目录,如果原来的目录已经存在,将自动备份,如果该目录不存在,将自动创建        /// </summary>        /// <param name="physicalPath"></param>        /// <param name="zipFile"></param>        /// <returns></returns>        private  string CheckWebSiteFolder(string physicalPath, string zipFile)        {            string webSiteFolder = System.IO.Path.Combine(physicalPath, System.IO.Path.GetFileNameWithoutExtension(zipFile));            if (System.IO.Directory.Exists(webSiteFolder))            {                System.IO.Directory.Move(webSiteFolder, webSiteFolder + "_back" + DateTime.Now.ToString("yyyyMMddHHmmss"));            }            //此目录            return webSiteFolder;

 7,给MVC页面传递数据

可以使用ViewBag 方式,例如下面的方式:

 public ActionResult Index(string zipFile="",string message="")        {            string iisVersion = IISControlHelper.IISWorker.GetIIsVersion();            ViewBag.IISVerion = iisVersion;            ViewBag.ZipFile = zipFile;            ViewBag.Message = message;                      return View();        }

ViewBag 是动态类型,在前端页面直接使用它既可。

也可以通过Action传递一个对象给页面,方法如下:

 public ActionResult Index(string zipFile="",string message="") {      var siteList = IISControlHelper.IISWorker.GetServerBindings();      return View(siteList); }

然后,在 index.cshtml 页面的头部,引入这个Model:

@model List<IISControlHelper.IISInfo>@{    ViewBag.Title = "ASP.NET在线创建网站Demo";}
