Delegate with a main method

Question

I can't access my delegate in the main method. I think it has something to do with the static main. But I can't make my delegate static.

public delegate double Calculation(double number1, double number2);

static void Main(string[] args)
{
}

Answer 1

The delegate type you declared can certainly be used from Main:

public delegate double Calculation(double number1, double number2);

public static void Main(string[] args)
{
    Calculation x = null;
}

Most likely you are confused about using delegates in general, and the static method Main has nothing to do with your problem whatsoever.
