A type parameter can be used as a constraint

    


    using System;
    using System.Collections;

    public class Test{
        public static void Main(){
           X<Y, Z> obj=new X<Y, Z>();
        }
    }

    public class Z {
        public void MethodA() {
            Console.WriteLine("Y::MethodA");
        }
    }

    public class Y: Z {
    }

    public class X<T1, T2> where T1:T2 {
        public void MethodB(T1 arg) {

        }
    }
