Question

I want to process the http request in thread, the code as follow where the problem is that OutputStream (as noted in codes) can not be writen. When I put this process in main thread, it’s no problem. Can you give me any advice?

    public partial class MainWindow : Window
    {
       private void Window_Loaded(object sender, RoutedEventArgs e)
       {
            var server = new HttpServer();
            try
            {
                server.EndPoint = new IPEndPoint(127.0.0.0, 80); //set webServer para
                server.Start(); //start webServer
                server.RequestReceived += server_RequestReceived; //register the event
            }
            catch (Exception ex)
            {
                return;
            }
       }
       private void server_RequestReceived(object sender, HttpRequestEventArgs e)
       {
           var dataProcess = new Action<HttpRequestEventArgs>(DataProcess);
           Dispatcher.BeginInvoke(dataProcess,e); //start thread
       }
       private void DataProcess(HttpRequestEventArgs e)
       {
           StreamReader sr = new StreamReader(@"c:\test.txt");
           string text = sr.ReadToEnd();
           using (var writer = new StreamWriter(e.Response.OutputStream)) //**Cannot write stream**
           {
               writer.Write(text);
           }
           sr.Close();
       }
    }

I think your request is being close before the new thread runs. What you can do is to execute the whole request in the new thread. Something like:

public partial class MainWindow : Window
{
   private void Window_Loaded(object sender, RoutedEventArgs e)
   {
        var start = new Action<HttpRequestEventArgs>(Start);
        Dispatcher.start(start,e); //start thread
   }

   private void Start(HttpRequestEventArgs e)
   {
        var server = new HttpServer();
        server.EndPoint = new IPEndPoint(127.0.0.0, 80); //set webServer para
        server.Start(); //start webServe
        server.RequestReceived += server_RequestReceived; //register the event
   }

   private void server_RequestReceived(object sender, HttpRequestEventArgs e)
   {
       StreamReader sr = new StreamReader(@"c:\test.txt");
       string text = sr.ReadToEnd();
       using (var writer = new StreamWriter(e.Response.OutputStream)) //**Cannot write stream**
       {
           writer.Write(text);
       }
       sr.Close();
   }
}
