using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;/// <summary>

/// </summary>
public class MyHandler : IHttpHandler
{
    public MyHandler()
    {
        //
        // TODO: 在此处添加构造函数逻辑
        //
    }    #region IHttpHandler 成员    public bool IsReusable
    {
        get { return false; }
    }    public void ProcessRequest(HttpContext context)
    {
        context.Response.Write("DuoTian");
        string path = context.Request.RawUrl;
        context.Server.Transfer(path.Replace(".html", ".aspx"));
    }    #endregion
}<httpHandlers>
<add verb="*" path="*.html" type="MyHandler"/>
</httpHandlers>

Answer 2

context.Server.Transfer(path.Replace(".html", ".aspx")); 
这句有问题, 应该是: Server.Execute(path.Replace(".aspx", ".html")); 

Answer 3

地址栏的文件扩展名还是没有改变，需要配置IIS吗？

Answer 4

  public class UrlRewriter : IHttpHandler 
                {
                 public UrlRewriter()
                {
             
                }
                public void ProcessRequest(HttpContext Context)
                {
                try
                {
                string Url = Context.Request.RawUrl;
                     System.Text.RegularExpressions.Regex Reg = new System.Text.RegularExpressions.Regex(@"/show-(\d+)-(\d+)\..+",System.Text.RegularExpressions.RegexOptions.IgnoreCase);
                System.Text.RegularExpressions.Match m =
               Reg.Match(Url,Url.LastIndexOf("/"));
                if (m.Success)
                {
                String RealPath =  @"~/aspx/show.aspx?type=" + m.Groups[1] + "&id=" + m.Groups[2];
                Context.Server.Execute(RealPath);
                }
                else 
                               {
                Context.Response.Redirect(Context.Request.Url.ToString());
                }
                }
                catch
                {
                Context.Response.Redirect(Context.Request.Url.ToString());
                }
                }
    
                public bool IsReusable
                {
                get { return false; }
                }
                }
                 
在<system.web>节点下添加如下代码：
            <httpHandlers>
                <add verb="*" path="*/show-?*-?*.aspx" type="UrlRewriter" />
                </httpHandlers>
