从简单的例子理解泛型
话说有家影视公司选拔偶像派男主角，导演说了，男演员，身高是王道。于是有下面代码：
 

    public Boy(string name, int height) {
        this.mName = name;
        this.mHeight = height;
    }
}

 
//演员选拔类
public class Compare
{
    //导演导超女出生，喜欢一对一PK
    public Boy WhoIsBetter(Boy boy1, Boy boy2)
    {
        if (boy1.Height > boy2.Height)
        {
            return boy1;
        }
        else
        {
            return boy2;
        }
    }
}

 
//测试
static void Main(string[] args)
{
    Boy boy1 = new Boy(\"潘长江\", 165);
    Boy boy2 = new Boy(\"刘德华\", 175);

    Console.WriteLine(new Compare().WhoIsBetter(boy1, boy2).Name);
    Console.ReadLine();
}
