如何将C#对象转换为.NET中的JSON字符串? [英] How do I turn a C# object into a JSON string in .NET?

问题描述

我有这样的课程:

class MyDate
{
    int year, month, day;
}

class Lad
{
    string firstName;
    string lastName;
    MyDate dateOfBirth;
}

我想将Lad对象变成这样的JSON字符串:

And I would like to turn a Lad object into a JSON string like this:

{
    "firstName":"Markoff",
    "lastName":"Chaney",
    "dateOfBirth":
    {
        "year":"1901",
        "month":"4",
        "day":"30"
    }
}

(不带格式).我找到了此链接，但它使用的是不在.NET 4中的名称空间.我也听说过 JSON.NET ，但它们该站点目前似乎已关闭，并且我不希望使用外部DLL文件.除了手动创建JSON字符串编写器外，还有其他选择吗?

(without the formatting). I found this link, but it uses a namespace that's not in .NET 4. I also heard about JSON.NET, but their site seems to be down at the moment, and I'm not keen on using external DLL files. Are there other options besides manually creating a JSON string writer?

推荐答案

您可以使用

You could use the JavaScriptSerializer class (add reference to System.Web.Extensions):

using System.Web.Script.Serialization;

var json = new JavaScriptSerializer().Serialize(obj);

完整示例:

using System;
using System.Web.Script.Serialization;

public class MyDate
{
    public int year;
    public int month;
    public int day;
}

public class Lad
{
    public string firstName;
    public string lastName;
    public MyDate dateOfBirth;
}

class Program
{
    static void Main()
    {
        var obj = new Lad
        {
            firstName = "Markoff",
            lastName = "Chaney",
            dateOfBirth = new MyDate
            {
                year = 1901,
                month = 4,
                day = 30
            }
        };
        var json = new JavaScriptSerializer().Serialize(obj);
        Console.WriteLine(json);
    }
}
