c#之如何解析包含 C# 列表的 Json WebApi 响应

嗨，我有一个像

{"Status":"Success","Message":"Authentication successful","Data":{"Key":"sdsdIRs99Iebe6QHmawlBsCks9mqfUt6jKYNQ%2bW","UserId":"ddjjj8-11e6-637af7"}}

我如何解析它以读取响应。

我是这样做的:

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”和“消息”但无法读取“ key ”和“用户 ID”值。

请帮忙!

请您参考如下方法:

您可以使用 Newtonsoft Json 而不是 JavaScriptSerializer 您的 json 的类结构如下所示

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; } 
} 

反序列化可以很容易地完成，就像

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