Question

base on msdn pages, when we declare a delegate we do need to specify return value and also argument of the method that would be called via delegate.

my question:

let’s say I have a method as:

public int MethodA(bool bValue) and also void MethodB(int iValue)

Do I need to declare two different delegates here for each method or I can do it using one?

Thanks.

Do I need to declare two different delegates here for each method or I can do it using one?

Since these methods have completely different signatures, you need different delegates. However, you can use the built-in Func<bool, int> and Action<int> delegates instead of declaring your own delegate types.

For example, you could use:

Func<bool,int> delegateA = this.MethodA;

Action<int> delegateB = this.MethodB;
// or:  Action<int> delegateB = new Action<int>(this.MethodB);
