如何解析包含C＃列表的JSON WebAPI响应

Question

嗨，我有一个json响应，例如

{"状态"："成功"，"消息"："身份验证 成功"，"数据"：{" key"：" sdsdirs9iebe6qhmawlbscks9mqfut6jkynq％2bw"，" userId"：" ddjjj8-11e6-637af7}}}

我如何解析此响应。

我正在这样做：

private void POST(string url) 
{
    HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
    request.Method = "POST";
    System.Text.UTF8Encoding encoding = new System.Text.UTF8Encoding();
    postData="{"UserName": "abc"," +""Password": "mypwd"}";
    Byte[] byteArray = Encoding.UTF8.GetBytes(postData);
    request.ContentLength = byteArray.Length;
    request.ContentType = @"application/x-www-form-urlencoded";
    using (Stream dataStream = request.GetRequestStream())
    {
        dataStream.Write(byteArray, 0, byteArray.Length);
    }
    long length = 0;
    try 
    {
        using (HttpWebResponse response =  (HttpWebResponse)request.GetResponse())
        {
            length = response.ContentLength;
             using (var reader = new StreamReader(response.GetResponseStream()))
             {
                JavaScriptSerializer js = new JavaScriptSerializer();
                var objText = reader.ReadToEnd();
                string str= objText;
                MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));           
            }
        }                       
    }
    catch (WebException ex) 
    {
        // Log exception and throw as for GET example above
    }
}

我能够读取"状态"one_answers"消息"，但无法读取"键"one_answers"用户ID"值。

请帮助！

Answer 1

您可以使用Newtonsoft Json而不是JavaScriptSerializer JSON的类结构看起来像

public class Rootobject
{
    public string Status { get; set; }
    public string Message { get; set; }
    public Data Data { get; set; }
}
public class Data
{
    public string Key { get; set; }
    public string UserId { get; set; }
}

可以像

那样轻松地进行挑战

Rootobject ro = JsonConvert.DeserializeObject<Rootobject>(json);
Console.WriteLine(ro.Status + ", " + ro.Message + ", " + ro.Data.Key + ", " + ro.Data.UserId);

Answer 2

猜测（因为我们不知道MyObject类的结构）如何访问数据：

String status = myobj.status;
String message = myobj.message; 

现在，由于其他数据属性在JSON的"数据"节点中，因此您应该能够这样访问它们：

String key = myobj.data.key;
String userId = myobj.data.userId;
