C＃ - 如何在变量名中使用无效字符 [英] C# - how to use invalid characters in a variable name

问题描述

在C＃中，我建设，最终将被序列化到一些外部定义JSON类（这里简化了讨论目的）：

In C#, I'm building a class (simplified here for discussion purposes) that eventually will be serialized into some externally defined JSON:

    { 
    "$schema": "http://example.com/person.json",
    "name": "John",
    "age": 86
    }

在我的代码，我会是这样的：

In my code I would have something like:

public class Person
{
    public const string $schema= @"http://example.com/person.json";
    public string name {get;set; }
    public int age {get; set;}
}

...

...

 Person person = new Person();
 person.name = "John";
 person.age = 88;

 JavaScriptSerializer serializer = new JavaScriptSerializer();
 string json = serializer.Serialize(person);

在我的代码$架构上面是造成意外字符$的错误。有没有解决方法吗？

In my code above the $schema is causing an "Unexpected character '$' error. Is there a workaround?

推荐答案

提供属性 [DataContract] 你的人类。

另外，你的意思是让模式 常量？

Also, did you mean to make schema const?

[DataContract]
public class Person
{
    [DataMember(Name = "$schema")]
    public string schema { get; set; }
    public string name { get; set; }
    public int age {get; set;}
}
