Regex 正则 如何把斜杠打出来

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

  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.html指向NewsCount.aspx?id=1

我现在想把News-1.html改成News/1.html

请问应该怎么改

我把@".+News-(\d+).html" 改成@".+News/(\d+).html" 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



[解决办法]
Regex reg = new Regex(".+News-(\\d+).html");


[解决办法]
或者在字符串前加一个@转义
[解决办法]

C# code

 string input = "News-1.html"; string pattern = @"(?<=News)-(\d+)(?=\.html)"; input = System.Text.RegularExpressions.Regex.Replace(input, pattern, @"/$1");
[解决办法]
探讨

C# code


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

[解决办法]
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+).html");    HttpContext.Current.RewritePath(reg.Replace(HttpContext.Current.Request.Url.AbsolutePath, "News/$1.html"));｝//或者是这样void Application_BeginRequest(object sender, EventArgs e){    Regex reg = new Regex(@"News-(\d+).html");    HttpContext.Current.RewritePath(reg.Replace(HttpContext.Current.Request.Url.AbsolutePath, "News/$1.html"));｝

整这么麻烦干嘛？
用伪静态，直接写在webconfig就行。
