A generic delegate.

using System;  
  
delegate T SomeOp<T>(T v);  
  
class MainClass {  
  static int sum(int v) { 
    return v; 
  } 
 
  static string reflect(string str) { 
    return str; 
  } 
      
  public static void Main() {   
    SomeOp<int> intDel = sum;  
    Console.WriteLine(intDel(3)); 
 
    SomeOp<string> strDel = reflect;  
    Console.WriteLine(strDel("Hello")); 
  }  
}
