C＃4.0中的異步HTTP POST

我用下面的代碼在C＃中執行異步HTTP請求。C＃4.0中的異步HTTP POST

private static Task GetUrl(string url) 
    { 
     var request = (HttpWebRequest)WebRequest.Create(url); 
     request.UserAgent = 
      "Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/30.0.1599.69 Safari/537.36"; 
     request.Accept = "text/html"; 
     return Task 
      .Factory 
      .FromAsync<WebResponse>(request.BeginGetResponse, request.EndGetResponse, url) 
      .ContinueWith(t => 
      { 
       if (t.IsCompleted) 
       { 
        using (var stream = t.Result.GetResponseStream()) 
        { 
         using (var reader = new StreamReader(stream)) 
         { 
          //Console.WriteLine("-- Successfully downloaded {0} --", t.AsyncState); 
          //Console.WriteLine(reader.ReadToEnd()); 
         } 
        } 
       } 
       else if (t.IsFaulted) 
       { 
        Console.WriteLine("There was an error downloading {0} - {1}", t.AsyncState, t.Exception); 
       } 
      }); 
    }

但是我不知道我應該如何修改上面的代碼來支持HTTP POST。任何幫助表示讚賞！

我特別想知道我應該如何添加BeginGetRequestStream和EndGetRequestStream到當前的功能...

只要搜索「的WebRequest POST 「，這很簡單，並且[這裏是]（http://msdn.microsoft.com/en-us/library/debx8sh9.aspx）一個鏈接......它與你的其他代碼無關，你只需要以不同的方式配置您的WebRequest。 –

使用HttpWebRequest的方法屬性：

request.Method = "POST";
