C#: the sample usage of c# template

1. class definition with constraints

 

1 class Test<T, V> where V:MyType {
2         public String name;
3         public T value;
4         public virtual void print() {
5             Console.WriteLine("{0}={1}", name, value);
6         }//print()
7     } //class

 

2. inherited class definition with constraint( my use constraint)

 

1     
2     class Test2<T1,T2>  : Test<T1,T2>  where T2:MyType{
3         public override void print() {
4             Console.WriteLine("IN Test2");
5             base.print();
6         }//print()
7         
8     }

 

3. template in method(static and non-static)

 

1         public static void testme<T>(T val) where T:IHoho, IOK{
2             Console.WriteLine(val);
3         }
4         public void testme2<T>(T val) {
5             Console.WriteLine(val);
6         }

 

4. Usage

 

 1         public static void Main(string[] args)
 2         {
 3             Test<int, MyType2> intValue = new Test<int, MyType2>();
 4             intValue.name = "int";
 5             intValue.value = 100;
 6             intValue.print();
 7             Test2<float, MyType2> floatValue = new Test2<float, MyType2>();
 8             floatValue.name = "float";
 9             floatValue.value = 200.10F;
10             floatValue.print();
11             testme(new MyType2(100));
12             testme(new MyType2("Hello"));
13             new Program().testme2("World");
14             
15         }
