如何从C语言中获取JSON数组的数据?

你可以得到每一个这样的值,那么就取决于你需要选择哪一个值。

    foreach (JObject content in test1.Children<JObject>())
    {
          string Id = content["id"].ToString();
          string email = content["email"].ToString();
    }

下面是正确格式化的json。

[{"id":11,"userName":null,"passWord":null,"email":"someone@gmail.com","mobile":"9423422882","fullName":"Ramesh Sharma","location":"Rajkot","city_id":1}]

在对您的问题的评论中,您说您的json是:

[
  {
    "id": 11,
    "userName": null,
    "passWord": null,
    "email": "someone@gmail.com",
    "mobile": "9898989898",
    "fullName": "Ramesh Sharma",
    "location": "Rajkot",
    "city_id": 1
  }
]

为json创建c类,如图所示 here 你会得到这些课程:

public class Rootobject
{
    public Class1[] Property1 { get; set; }
}

public class Class1
{
    public int id { get; set; }
    public object userName { get; set; }
    public object passWord { get; set; }
    public string email { get; set; }
    public string mobile { get; set; }
    public string fullName { get; set; }
    public string location { get; set; }
    public int city_id { get; set; }
}

然后反序列化如下:

var results = JsonConvert.DeserializeObject<RootObject>(yourJSON);
