Asp.net 如何将 JSON 对象转换为自定义 C# 对象

发布于02月12日

有没有一种简单的方法可以用通过AJAX传递的JSON对象填充我的C#对象？

这是使用JSON从页面传递给C#WEBMETHOD的JSON对象.严格化

{
    "user": {
        "name": "asdf",
        "teamname": "b",
        "email": "c",
        "players": ["1", "2"]
    }
}

接收JSON对象的C#WebMetod

[WebMethod]
public static void SaveTeam(Object user)
{

}

类，表示传递给WebMethod的JSON对象的对象 struct

public class User
{
    public string name { get; set; }
    public string teamname { get; set; }
    public string email { get; set; }
    public Array players { get; set; }
}

推荐答案

在C#中使用JSON的一个好方法是使用JSON.NET

JSON.NET - Official site分中的Quick Starts & API Documentation分能帮你解决这个问题.

如何使用它的示例:

public class User
{
    public User(string json)
    {
        JObject jObject = JObject.Parse(json);
        JToken jUser = jObject["user"];
        name = (string) jUser["name"];
        teamname = (string) jUser["teamname"];
        email = (string) jUser["email"];
        players = jUser["players"].ToArray();
    }

    public string name { get; set; }
    public string teamname { get; set; }
    public string email { get; set; }
    public Array players { get; set; }
}

// Use
private void Run()
{
    string json = @"{""user"":{""name"":""asdf"",""teamname"":""b"",""email"":""c"",""players"":[""1"",""2""]}}";
    User user = new User(json);

    Console.WriteLine("Name : " + user.name);
    Console.WriteLine("Teamname : " + user.teamname);
    Console.WriteLine("Email : " + user.email);
    Console.WriteLine("Players:");

    foreach (var player in user.players)
        Console.WriteLine(player);
 }
