Regex 正则如何把斜杠打出来_ASP.NET

Regex 正则怎么把斜杠打出来
void Application_BeginRequest(object sender, EventArgs e)
{
Regex reg = new Regex(@".+News-(\d+)");

var match = reg.Match(HttpContext.Current.Request.Url.AbsolutePath);

if (match.Success)
{
String id = match.Groups[1].Value;

HttpContext.Current.RewritePath("NewsCount.aspx?id="+id);
}
｝

在Global.asax中写的代码

如：News-1指向NewsCount.aspx?id=1

我现在想把News-1改成News/1

请问应该怎么改

我把@".+News-(\d+)" 改成@".+News/(\d+)" 不过不行

网上搜了一段时间也没弄明白

水平不行还请高手指教一下谢谢了

------解决方案--------------------------------------------------------
Regex reg = new Regex(".+News-(\\d+)");

------解决方案--------------------------------------------------------
或者在字符串前加一个@转义
------解决方案--------------------------------------------------------

C# code

 string input = "News-1"; string pattern = @"(?<=News)-(\d+)(?=\)"; input = System.Text.RegularExpressions.Regex.Replace(input, pattern, @"/$1");
------解决方案--------------------------------------------------------
探讨
C# code


 string input = "News-1";
 string pattern = @"(?<=News)-(\d+)(?=\)";
 input = System.Text.RegularExpressions.Regex.Replace(input, pattern, @"/$1");

------解决方案--------------------------------------------------------
try...

按你的需求
C# code//要么是这样void Application_BeginRequest(object sender, EventArgs e){    Regex reg = new Regex(@".+News-(\d+)");    HttpContext.Current.RewritePath(reg.Replace(HttpContext.Current.Request.Url.AbsolutePath, "News/$1"));｝//或者是这样void Application_BeginRequest(object sender, EventArgs e){    Regex reg = new Regex(@"News-(\d+)");    HttpContext.Current.RewritePath(reg.Replace(HttpContext.Current.Request.Url.AbsolutePath, "News/$1"));｝
------解决方案--------------------------------------------------------
整这么麻烦干嘛？
用伪静态，直接写在webconfig就行。
