C# 中类似 JSON 的对象的实际类型是什么 (new {};)

Question

I was learning C# and found that there is some type of value defined by

var json = new {name="App", age=20};

Although this seems to be similar to the JSON type. But when I tried to use the GetType method, I got <>f__AnonymousType0`2[System.String,System.Int32]

Can anyone help me in this please?

In case you want the full code

using System;

public class Program
{
    public static void Main()
    {
        var c = new { name="App", age=22 };

        Console.WriteLine(c.GetType());
        Console.WriteLine(c);;
    }
}

It's called Anonymous Type and it has no relation to JSON.

You can read about it FROM MSDN

Anonymous types provide a convenient way to encapsulate a set of read-only properties into a single object without having to explicitly define a type first. The type name is generated by the compiler and is not available at the source code level. The type of each property is inferred by the compiler.
