Using a Delegate with Messages

I'm learning about delegates and think I may have found a use for one. Basically what I have is a series of string properties that take in a minimum value and a maximum value, like so:

string weightInvalid(min as int32, max as int32)

There are several messages like this, all with unique messages but all sharing the same signature of minimum and maximum. I think that a delegate could be used here, but how would I go about doing so? It would really help me to see some code so I could get a grasp on this delegate stuff.

From stackoverflow

• on c#:

  delegate string weightInvalid(int min, int max);
  
  string MyWeightInvalid(int min, int max)
  {
      return "";
  }
  
  string SomeMethod()
  {
  
      weightInvalid myFunc = new weightInvalid(MyWeightInvalid);
      return myFunc(0, 1);
  }
  

• Below is a simple Console application example that may help...

  public delegate string foo(int min, int max);
  
      class Program
      {
          static void Main(string[] args)
          {
              CallFoo(foo1);
              CallFoo(foo2);
              CallFoo(foo3);
  
              Console.WriteLine("Press ENTER to exit...");
              Console.ReadLine();
          }
  
          private static void CallFoo(foo foo)
          {
              Console.WriteLine(foo(1, 2));
          }
  
          private static string foo1(int min, int max)
          {
              return "foo1";
          }
  
          private static string foo2(int min, int max)
          {
              return "foo2";
          }
  
          private static string foo3(int min, int max)
          {
              return "foo3";
          }
  

  Austin : Thanks. I think I've managed to implement this. I just needed to get a picture of exactly how something like this would work. However, I'm still confused as to why this would be useful. Is this a practical use for something like I'm wanting to do?
