如何发送数据以验证服务器？使用当前代码：

WebClient MyWebClient = new WebClient();
        MyWebClient.OpenWriteCompleted += new OpenWriteCompletedEventHandler(MyWebClient_OpenWriteCompleted);
        MyWebClient.Headers["User-Agent"] = "Mozilla/4.0 (compatible; ICS)";
        MyWebClient.OpenWriteAsync(new Uri("http://myserver.com/login"), "POST", "email=myemail@server.com&pass=mypassword");


    void MyWebClient_OpenWriteCompleted(object sender, OpenWriteCompletedEventArgs e)
    {
        throw new NotImplementedException();
    }

在此代码之后，如果程序嗅探器（HttpAnalyzer）查看Headers和Response Content，则在响应内容中将写入：Request is not completed. waiting ...，响应标头将为空... 如何发表帖子请求？

Answer 1

根据doc，当您关闭在OpenWriteCompleted事件的参数中传递给您的流时，实际上会发送内容。

由于您没有正确关闭流，因此不会发送任何内容。

Answer 2

//Making a POST request using WebClient.


Function()
{    
  WebClient wc = new WebClient();

  var URI = new Uri("http://your_uri_goes_here");

//如果需要任何编码。

  wc.Headers["Content-Type"] = "application/x-www-form-urlencoded";

//或任何其他编码类型。

//如果需要任何密钥

  wc.Headers["KEY"] = "Your_Key_Goes_Here";

 wc.UploadStringCompleted += new UploadStringCompletedEventHandler(wc_UploadStringCompleted);

 wc.UploadStringAsync(URI,"POST","Data_To_Be_sent");

}

void wc__UploadStringCompleted(object sender, UploadStringCompletedEventArgs e)

{  

  try            
  {          
     MessageBox.Show(e.Result);

// e.result会根据您的POST请求获取响应。

 }

  catch(Exception exc)         
  {             
     MessageBox.Show(exc.ToString());            
  }

}
