    public static void DoWork()
    {
        int a = 3;
        // Pointer to a static function
        AddOneDgt addOneFctPtr = new AddOneDgt(A.AddOne);
        // Pointer to an instance function
        AddOneDgt addOneFctPtr1 = new AddOneDgt(new A().AddOneInst);
        // C# 2.0 - Anonymous functions
        AddOneDgt addOneInlinePtr = new AddOneDgt(delegate(int x) { return x + 1; }); 
        // C# 3.0 - Lambda
        AddOneDgt addOneLambdaPtr = x => x + 1;

        Console.WriteLine(string.Format("A. {0} + 1 = {1}", a, addOneFctPtr(a)));
        Console.WriteLine(string.Format("B. {0} + 1 = {1}", a, addOneFctPtr1(a)));
        Console.WriteLine(string.Format("C. {0} + 1 = {1}", a, addOneInlinePtr(a)));
        Console.WriteLine(string.Format("D. {0} + 1 = {1}", a, addOneLambdaPtr(a)));
    }

    public class A
    {
        public static int AddOne(int x)
        {
            return x + 1;
        }

        public int AddOneInst(int x)
        {
            return x + 1;
        }
    }
}

Output:
A. 3 + 1 = 4
B. 3 + 1 = 4
C. 3 + 1 = 4
D. 3 + 1 = 4
