Question

Can anyone tell me how I can implement Call By Name in C#?

Answer 1

You can do that using Reflection:

using System;
using System.Reflection;

class CallMethodByName
{
   string name;

   CallMethodByName (string name)
   {
      this.name = name;
   }

   public void DisplayName()      // method to call by name
   {
      Console.WriteLine (name);   // prove we called it
   }

   static void Main()
   {
      // Instantiate this class
      CallMethodByName cmbn = new CallMethodByName ("CSO");

      // Get the desired method by name: DisplayName
      MethodInfo methodInfo = 
         typeof (CallMethodByName).GetMethod ("DisplayName");

      // Use the instance to call the method without arguments
      methodInfo.Invoke (cmbn, null);
   }
}
