使用JavaScriptSerializer实现Date对象的自定义序列化

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

public class CustomJavaScriptSerializer : JavaScriptSerializer
{
    public override object Serialize(object obj)
    {
        if (obj is DateTime)
        {
            DateTime date = (DateTime)obj;
            return date.ToString("yyyy-MM-dd HH:mm:ss");
        }
        return base.Serialize(obj);
    }
}

public class MyClass
{
    public DateTime Date { get; set; }
}

public class Program
{
    public static void Main(string[] args)
    {
        CustomJavaScriptSerializer serializer = new CustomJavaScriptSerializer();
        MyClass myObject = new MyClass { Date = DateTime.Now };
        string json = serializer.Serialize(myObject);
        Console.WriteLine(json);
    }
}
