反序列化json时获取null

Question

I am trying to deserialize my web response json to an object, at the time object getting null after deserialization. 我正在尝试将我的网络响应json反序列化为一个对象，当时反序列化之后对象变为null 。 This is my code: 这是我的代码：

JSON response: JSON响应：

}

Deserialization: 反序列化：

JavaScriptSerializer json = new JavaScriptSerializer();
value condiiton = (value)json.Deserialize(responcedata, typeof(value));

Let's look at your JSON object. 让我们看一下您的JSON对象。 You actually have an anonymous JSON (let's call it response ) object with two objects: string '@odata.context' and array 'value' of objects of value C# class type. 实际上，您有一个带有两个对象的匿名JSON对象（我们称其为response ）：字符串'@ odata.context'和value C＃类类型的对象的数组'value'。

You have described value class but now you are trying do deserialize response object to value which is incorrect. 您已经描述了value类，但是现在您尝试将response对象反序列化为不正确的value 。
You need to describe the corresponding class and deserialize it. 您需要描述相应的类并将其反序列化。

public class Response 
{
    public value[] value { get; set; }
}

Then you can do it this way: 然后，您可以通过以下方式进行操作：

JavaScriptSerializer json = new JavaScriptSerializer();
Response response = (Response)json.Deserialize(responcedata, typeof(Response));
