Hi,  
I do not understand your problem.  
Can you be more specific?  
What are you trying to do ?  
Regards.

I’m sorry to say, but to me it is still pretty vague. I don’t understand what delegates have to do in this.  
Can you provide a clear example ?

Because to me as is it looks just like

```nohighlight
public static bool MyMethod(int n1, int n2){
	// Some validation logic. For instance
	return (n1 == 2*n2);
}

```

In C#, a delegate is a type that represents a reference to a method. It can be used to pass methods as arguments to other methods or to store methods as variables. To validate multiple user input integers using a [C# delegate](http://net-informations.com/faq/net/delegates.htm), you can define a method that takes an integer as input and returns a boolean value indicating whether the input is valid or not. You can then create a delegate that points to this method and use it to validate each user input integer.
