C# 3.0--对象初始化语法

可以不必为了给属性赋值而写很多的构造函数重载了。节约了代码量。

注：Test本身的构造函数会被执行，即Console.WriteLine("Test constructor");

using System;

using System.Collections;

using System.Linq;

using System.Text;

using System.Collections.Generic;

using System.Runtime.Serialization;

using System.Text.RegularExpressions;



namespace TestCS

{

    public class Test

    {

        public int X;

        public int Y;



        public Test2 t;



        public Test()

        {

            Console.WriteLine("Test constructor");

        }

        public override string ToString()

        {

            return X.ToString() + "," + Y.ToString() + "," + t.ToString();

        }

    }



    public class Test2

    {

        public int Z;



        public override string ToString()

        {

            return "In Test2--"+Z.ToString();

        }

    }





    public class Progarm

    {

        public static void Main(string[] args)

        {

            Test t = new Test() { X = 1, Y = 2, t = new Test2() { Z = 3 } };

            Console.WriteLine(t.ToString());

        }



    }
