写了一个简单WebServer 服务器，可以处理js、css、html、aspx的请求，以及图片、视频

代码如下：

  public delegate void ProcessRequestHandler(string page, string query, TextWriter writer);    public class WebServer : MarshalByRefObject, IRegisteredObject    {        public void ProcessRequest(string page, string query, TextWriter writer)        {            SimpleWorkerRequest worker = new SimpleWorkerRequest(page, query, writer);            HttpRuntime.ProcessRequest(worker);        }        public void Stop(bool immediate)        {            HostingEnvironment.UnregisterObject(this);        }    }    public class SimpleHttpListener    {        ProcessRequestHandler ProcessRequest;        public void SetProcessRequest(ProcessRequestHandler handler)        {            this.ProcessRequest = handler;        }        static string PhysicRoot = string.Empty;         public void Run()        {            if (!HttpListener.IsSupported)                throw new InvalidOperationException("使用 HttpListener 必须为 Windows XP SP2 或 Server 2003 以上系统！");            string[] prefixes = new string[] { "http://localhost:49152/" };            HttpListener listener = new HttpListener();            foreach (string item in prefixes)            {                listener.Prefixes.Add(item);            }            listener.Start();            Console.WriteLine("开始监听.....");            while (true)            {                HttpListenerContext context = listener.GetContext();                HttpListenerRequest request = context.Request;                Console.WriteLine("{0} {1} HTTP/1.1", request.HttpMethod, request.RawUrl);                HttpListenerResponse response = context.Response;                using (StreamWriter writer = new StreamWriter(response.OutputStream))                {                    StringWriter sw = new StringWriter();                    string content = string.Empty;                    string filename = request.Url.LocalPath.ToLower();                    Regex reg = new Regex("(.aspx|.ashx|.svc|.asmx)");                    Match m = reg.Match(filename);                    if (m.Success)                    {                        string path = request.Url.AbsolutePath;                        string query = request.Url.Query.Replace("?", string.Empty);                        string prefx = m.Groups[0].Value;                        if (!filename.EndsWith(prefx))                        {                            int index = path.IndexOf(prefx);                            index = index + prefx.Length;                            query = path.Substring(index);                            path = path.Substring(0, index);                        }                        path = Path.GetFileName(path);                        this.ProcessRequest(path, query, sw);                        content = sw.ToString();                        sw.Close();                        response.ContentLength64 = Encoding.UTF8.GetByteCount(content);                        response.ContentType = "text/html;
