在C＃中的WebClient阅读响应头 [英] Read response header from WebClient in C#

问题描述

我试图创建我的第一个Windows客户端（这是我的拳头张贴她的），须以网络服务沟通，但我有一些麻烦读取响应头有回来。在我响应字符串我收到了很好的JSON文件后面（这是我的下一个问题），但我不能够看到/阅读在响应头，只有身体。

$ B $ ; b

下面是我使用的代码

  WebClient的MyClient =新的WebClient（）; 
 MyClient.Headers.Add（内容类型，应用/ JSON）; 
 MyClient.Headers.Add（用户代理，DIMS /0.1 + HTTP：//www.xxx.dk）; 
 VAR urlstring =http://api.xxx.com/users/+ Username.Text; 
串响应= MyClient.DownloadString（urlstring.ToString（））; 
  

解决方案

您可以使用WebClient.ResponseHeaders这样的：

  //获得包含从响应头名称/值对的WebHeaderCollection实例。 
 WebHeaderCollection myWebHeaderCollection = myWebClient.ResponseHeaders; 
 
 Console.WriteLine（\\\
Displaying响应headers\\\
）; 
 //循环responseHeaders和显示标题名称/值对。 
表示（INT I = 0; I&下; myWebHeaderCollection.Count;我++）
 Console.WriteLine（\t+ myWebHeaderCollection.GetKey（I）+=+ myWebHeaderCollection.Get（ⅰ ））;

I'm trying to create my first windows client (and this is my fist post her), there shall communicate with a "web services", but i have some trouble to read the response header there is coming back. In my response string do I received a nice JSON document back (and this is my next problem), but i'm not able to "see/read" the header in the response, only the body.

Below is the code i'm using.

        WebClient MyClient = new WebClient();
        MyClient.Headers.Add("Content-Type", "application/json");
        MyClient.Headers.Add("User-Agent", "DIMS /0.1 +http://www.xxx.dk");
        var urlstring = "http://api.xxx.com/users/" + Username.Text;
        string response = MyClient.DownloadString(urlstring.ToString());

解决方案

You can use WebClient.ResponseHeaders like this:

// Obtain the WebHeaderCollection instance containing the header name/value pair from the response.
WebHeaderCollection myWebHeaderCollection = myWebClient.ResponseHeaders;

Console.WriteLine("\nDisplaying the response headers\n");
// Loop through the ResponseHeaders and display the header name/value pairs. 
for (int i=0; i < myWebHeaderCollection.Count; i++)             
    Console.WriteLine ("\t" + myWebHeaderCollection.GetKey(i) + " = " + myWebHeaderCollection.Get(i));
