Question

So i have 2 classes named A and B.

A has a method “public void Foo()”.

B has several other methods.

What i need is a variable in class B, that will be assigned the Foo() method of class A.
This variable should afterwards be “executed” (=> so it should execute the assigned method of class A).

How to do this?

Answer 1

Reed gave you the right answer. It’s also worth pointing out that you can use other delegate signatures besides Action.

There are generic versions like Action<T> (one arg), Action<T1, T2> (two args), etc…
Also if your method has a return type, check out Func<T, TResult>.

• Action docs: http://msdn.microsoft.com/en-us/library/018hxwa8.aspx
• Func docs: http://msdn.microsoft.com/en-us/library/bb549151.aspx

Or of course you can define your own delegate type.
