C# 写配置文件 log4net

1.使用winform形式

①。AssemblyInfo.cs中增加[assembly: log4net.Config.XmlConfigurator(ConfigFile = "log4net.config", ConfigFileExtension = "config", Watch = true)]

②。引用log4net   Log4Net.config

③。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using log4net;

namespace WindowsFormsSolaceTest
{
    class loghelp
    {
        //第四步：在项目文件根目录（其实无所谓，想建在哪里都是阔以滴）建一个LogHelper.cs类
        public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");
        public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");
        public static void WriteLog(string info)
        {
            if (loginfo.IsInfoEnabled)
            {
                loginfo.Info(info);
            }
        }

        public static void WriteLog(string info, Exception se)
        {
            if (logerror.IsErrorEnabled)
            {
                logerror.Error(info, se);
            }
        }
    }
}

④。loghelp.WriteLog("Error: " + args.Event.ToString());

服务中的使用

1.服务的 appcongfig中加入  

<configSections>
  <section name ="log4net" type="log4net.Config.Log4NetConfigurationSectionHandler, log4net" />
  <sectionGroup name="applicationSettings" type="System.Configuration.ApplicationSettingsGroup, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" >
    <section name="SolaceMessageServer.Properties.Settings" type="System.Configuration.ClientSettingsSection, System, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089" requirePermission="false" />
  </sectionGroup>

②。引用log4net   Log4Net.config

③。

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using log4net;
namespace SolaceMessageServer
{
    class LogHelper
    {
        public static readonly log4net.ILog loginfo = log4net.LogManager.GetLogger("loginfo");
        public static readonly log4net.ILog logerror = log4net.LogManager.GetLogger("logerror");
        public static readonly ILog _log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);
        public static void WriteLog(string info)
        {
            if (loginfo.IsInfoEnabled)
            {
                loginfo.Info(info);
            }
        }

        public static void WriteLog(string info, Exception se)
        {
            if (logerror.IsErrorEnabled)
            {
                logerror.Error(info, se);
            }
        }
    }
}
 

④。loghelp.WriteLog("Error: " + args.Event.ToString());
