c#中通过自定义隐式转换实现返回值重载

using System;

using System.Collections.Generic;

namespace CountStrDemo

{

class 返回值重载

{

public static void Main(string[] args)

{

//您看看这调用处,那叫一个完美

MyReturnDemo obj = new MyReturnDemo( "aladdin" , 22 );

int i = obj.GetInfo();

string str = obj.GetInfo();

Console.WriteLine( i.ToString() );

Console.WriteLine( str );

Console.ReadLine();

}

}

class MyReturnDemo

{

public string name;

public int age;

{

this.name = name;

this.age = age;

}

private string ReturnByString()

{

return "姓名 :" + this.name ;

}

private int ReturnByInt()

{

}

public MyStructTemp GetInfo()

{

}

//结构,用做中间处理.

public struct MyStructTemp

{

private MyReturnDemo stuobj;
