Gmail联系人/反序列化包含电子邮件的json对象

Question

我想获得gmail联系人(实际上是电子邮件联系人)，所以我在google控制台注册并获得了凭证，并且使用访问令牌获得了联系人。具有范围：

https://www.google.com/m8/feeds/ + https://www.googleapis.com/auth/contacts.readonly

并请求uri作为：

https://www.google.com/m8/feeds/contacts/default/full?alt=json

这给了我这样的结果：

要么我需要一种更好的方法从gmail中获取电子邮件联系人，要么我需要一种将这个json反序列化为类的方法，我试图通过将这个json转换成C#来反序列化，但是没有成功。让我知道能做些什么。

Answer 1

解决了我的问题，有时会出现'$t‘之类的实例，或者其中包含'$’的类似实例，当转换为C#类时，会导致无效的名称。要解决这个问题，添加dll引用'Newtonsoft.Json‘并创建一个类，使用名称空间作为’使用Newtonsoft.Json‘，并在每个属性中名称无效，如下所示；

public string __invalid_name__$t { get; set; }

添加Json属性，如下所示，并根据您的喜好更改名称：

[JsonProperty("$t")]
public string NameOfMyChoosing { get; set; }
