为什么这个匿名类型不反序列化正确使用JsonConvert.DeserializeAnonymousType？ [英] Why does this anonymous type not deserialize properly using JsonConvert.DeserializeAnonymousType?

问题描述

我的JSON字符串：

  {响应：{令牌：{\标记\：\123 \，\ID \：191}}}
 

然后，我有以下的code反序列化，但它返回空值：

  VAR高清=新
       {
           令牌=新{记号=的String.Empty，ID =的String.Empty}
        };

  VAR deserializedToken = JsonConvert.DeserializeAnonymousType（令牌，DEF）;
 

deserializedToken 为null

下面是一个更详细的例子，我不能去工作：

  VAR高清=新
            {
                code =的String.Empty，
                消息=的String.Empty，
                URL =的String.Empty，
                令牌=新{记号=的String.Empty}
            };

            VAR响应= JsonConvert.DeserializeAnonymousType（数据，DEF）;

            VAR innerDef =新{记号=的String.Empty，ID =的String.Empty};

            VAR deserializedInner = JsonConvert.DeserializeAnonymousType（response.token.token，innerDef）;
 

解决方案

有两个问题在这里，因为据我可以告诉：

• 您没有响应属性，反序列化
• 的令牌：123编号：191部分实际上只是一个字符串 - 的价值外标记属性

所以，如果你改变了code到：

  VAR高清=新
{
    响应=新{记号=}
};

VAR deserializedToken = JsonConvert.DeserializeAnonymousType（JSON，DEF）;
Console.WriteLine（deserializedToken）;
 

，那么你就可以结束：

  {响应= {记号= {令牌：123，ID：191}}}
 

如果你想反序列化令牌/ ID的一部分，以及，你可以做到这一点：

  VAR innerDef =新{记号=，ID =};
VAR deserializedInner = JsonConvert.DeserializeAnonymousType
    （deserializedToken.response.token，innerDef）;
Console.WriteLine（deserializedInner）;
 

这则打印：

  {记号= 123，n = 191}
 

I have the JSON string:

{"response":{"token":"{\"token\":\"123\",\"id\":191}"}}

And then I have the following code to Deserialize it, but it is returning null:

 var def = new
       {
           token = new { token = string.Empty, id= string.Empty }
        };

  var deserializedToken = JsonConvert.DeserializeAnonymousType(token, def);

deserializedToken is null

Here is a more detailed example that I can't get to work:

var def = new
            {
                code = string.Empty,
                message = string.Empty,
                url= string.Empty,
                token = new {token = string.Empty}
            };

            var response = JsonConvert.DeserializeAnonymousType(data, def);

            var innerDef = new { token= string.Empty, id= string.Empty };

            var deserializedInner = JsonConvert.DeserializeAnonymousType(response.token.token, innerDef);

解决方案

There are two problems here, as far as I can tell:

• You don't have a response property to deserialize
• The "token:123 id:191" part is actually just a string - the value of the outer token property

So if you change your code to:

var def = new
{
    response = new { token = "" }
};

var deserializedToken = JsonConvert.DeserializeAnonymousType(json, def);
Console.WriteLine(deserializedToken);

then you'll end up with:

{ response = { token = {"token":"123","id":191} } }

If you want to deserialize the token/id part as well, you can do that with:

var innerDef = new { token = "", id = "" };
var deserializedInner = JsonConvert.DeserializeAnonymousType
    (deserializedToken.response.token, innerDef);
Console.WriteLine(deserializedInner);

That then prints:

{ token = 123, id = 191 }
