在WinForm中通过HTTP协议向服务器端上传文件

在WinForm中通过HTTP协议向服务器端上传文件(23)       if (oArgs.Cancel)
       goto CloseDown;

    }
   } // while

  CloseDown:
   oHttpResponse.Close();

   // *** Send Done notification
   if (this.OnReceiveData != null && !oArgs.Cancel)
   {
    // *** Update the event handler
    oArgs.Done = true;
    this.OnReceiveData(this,oArgs);
   }

//   return lcHtml;
   return loWriter.ToString();
  }

  public delegate void OnReceiveDataHandler(object sender, OnReceiveDataEventArgs e);
  public class OnReceiveDataEventArgs
  {
   public long CurrentByteCount=0;
   public long TotalBytes = 0;
   public int NumberOfReads = 0;
   public char[] CurrentChunk;
   public bool Done = false;
   public bool Cancel = false;
  }  
 }

在wwHttp这个类里面，不仅仅可以传送文件AddPostFile方法，还可以传送变量AddPostKey方法。

这样，如果我们要通过代理服务器传送文件，就可以编写如下的代码了：
wwHttp ww = new wwHttp();
   ww.ProxyAddress = "202.132.156.124";   
   ww.PostMode = 2;
   ww.AddPostKey("testKey","test");
   ww.AddPostFile("myfile",@"D:\Temp\Java\JavaStart\JavaStart2.jar");  
   
   string shtml = ww.GetUrlEvents("http://localhost/UploadFileWeb/WebForm1.ASPx",409600);
