C# 泛型方法

static void Main(string[] args)
{  

  TestClass cls = new TestClass();
  cls.GetType("123");

  Student stu = new 泛型方法.Student();
  stu.Name = "王五";
  stu.Age = 23;

  //只有在使用才能确定类型
  cls.GetParam(stu);

 

  Console.ReadKey();

}



public class TestClass
{

     /// 
       /// object是任何类型的父类,都可以用子类的元素代替,实质进行类型的转换消耗了性能
       /// 
       /// 
        public void GetType(object tParam)
        {
       // tParam参数只有四个方法调用, Console.WriteLine(
"类型为:"+tParam.GetType()); } /// /// 泛型方法,T参数类型只有在使用时候才能确定类型,泛型方法进行约束,则T类型必须是People或其子类,否则程序会报错 /// /// /// public void ShowGeneric(T tParam) where T :People { Console.WriteLine("类型为:" + tParam.GetType() + " ,姓名为:" + tParam.Name);
       //SayHi()是People父类的方法 tParam.SayHi(); }
/// /// 泛型方法没有约束的 /// /// /// public void GetParam(T tParam) {
       // is 用于判断类型
if (tParam is Student) { Student stu = tParam as Student; Console.WriteLine("类型为:" + tParam.GetType() + "其他的" + stu.Name); } else Console.WriteLine("类型为:" + tParam.GetType()); }
