Lambda\Anonymous Function as a parameter

Question

I\'m a very new to C#. Just playing around with it. Not for a real purpose.

void makeOutput( int _param)
{
    Console.WriteLine( _param.ToString());
}

//..         


        

Answer 1

Yes.
It's called a delegate.

Delegates are (more-or-less) normal types; you can pass them to functions just like any other type.

void makeOutput(Func param) {
    Console.WriteLine(param());
}

makeOutput(delegate { return 4; });
makeOutput(() => { return 4; });
makeOutput(() => 4);

Your edited question does not make sense.

C# is type-safe.
If the method doesn't want a function as a parameter, you cannot give it a method as a parameter.
