What is Generic Delegates and its Types.

In C#, a generic delegate is a delegate that can work with any data type. This is achieved by using the Func or Action delegates along with generics.

Here's an example of a generic delegate using Func:

   
  
    using System;

    class Program
    {
        static void Main()
        {
            Func add = (a, b) => a + b;
            Func concatenate = (a, b) => a + b;

            Console.WriteLine(add(1, 2)); // Outputs: 3
            Console.WriteLine(concatenate("Hello, ", "world!"));
        }
    }


          
       
In this example, Func int, int, int is a generic delegate that takes two int parameters and returns an int.
  
     
Similarly, Func string, string, string takes two string parameters and returns a string.
          
          
          
  
 Action Delegates:
    
      
          
  🔸Action delegates are used for methods that do not return a value (void methods). They can take up to 16 input parameters.
     
 
          
    For example:
          
          
   
   
  
    Action logMessage = (message) => Console.WriteLine(message);
    logMessage("Hello, world!");


          
          

         🔸 use Action when you need a delegate for a void method.
         

          🔸use Func when you need a delegate for a method that returns a value.
