尝试使用System.Net.Http.Post时发生C＃错误消息

Question

我正在开发Windows 8应用程序。错误消息“当我尝试执行代码时，名为'System.Net.Http'（缺少程序集引用？”）的类型或名称空间名称'Post'将出现在Visual Studio 2012中“

byte[] response = System.Net.Http.Post 
    (
     url: "someurl", 
     contentType: "application/json", 
     contentLength: 32, 
     content: "pqpUserName=admin&[email protected]" 
); 

的代码是从URL .NET: Simplest way to send POST with data and read response

。任何帮助表示赞赏。

Answer 1

使用HttpClient：

var client = new HttpClient(); 

var pairs = new List<KeyValuePair<string, string>> 
       { 
        new KeyValuePair<string, string>("pqpUserName", "admin"), 
        new KeyValuePair<string, string>("password", "[email protected]") 
       }; 

var content = new FormUrlEncodedContent(pairs); 

var response = client.PostAsync("yourURI", content).Result; 

if (response.IsSuccessStatusCode) 
{} 

Answer 2

将System.Net.Http.HttpMethod命名空间添加到您的代码中。
