Using Delegate C#

How to validate multiple user input integers using delegate in C#?

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

I want to create application in visual studio but i want a method that i can parse multiple inputs to validate numbers/integers.

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

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