What does it mean () => mean (C # 3.0)

Question

What does () => mean in C #?

Hello everybody,

This is my first stackoverflow question.

I ran into something like

() => SomeClass.SomeMethod(param1, param2)

This is completely new to me, and I can’t understand what it is, what we call it, what it does,

how it works, etc.

What I'm looking for is an explanation of the same with a simple example that might be

understandable, and I can implement it in my program. It will be good if I can get

real-time script for this implementation.

I am using C # 3.0 with dotnet 3.5 platform.

Thank you very much in advance.
