阅读HttpwebResponse JSON响应，C＃ [英] reading HttpwebResponse json response, C#

问题描述

在我的应用程序之一，我正在从WebRequest的响应。这项服务是RESTful服务，将返回类似下面的JSON格式的结果是：

In one of my apps, I am getting the response from a webrequest. The service is Restful service and will return a result similar to the JSON format below:

{
    "id" : "1lad07",
    "text" : "test",
    "url" : "http:\/\/twitpic.com\/1lacuz",
    "width" : 220,
    "height" : 84,
    "size" : 8722,
    "type" : "png",
    "timestamp" : "Wed, 05 May 2010 16:11:48 +0000",
    "user" : {
        "id" : 12345,
        "screen_name" : "twitpicuser"
    }
}   

和这里是我当前的代码：

and here is my current code:

    byte[] bytes = Encoding.GetEncoding(contentEncoding).GetBytes(contents.ToString());
    request.ContentLength = bytes.Length;

    using (var requestStream = request.GetRequestStream()) {

        requestStream.Write(bytes, 0, bytes.Length);

        using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

            using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {

                //What should I do here?

            }

        }

    }

我怎样才能读取响应？我想要的网址和用户名。

How can I read the response? I want the url and the username.

推荐答案

首先，你需要一个对象

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

然后在这里

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

我还没有与测试分层对象你有，但是这应该给你访问到你想要的属性。

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

的JavaScriptSerializer System.Web.Script.Serialization
