C# Language Tutorial => Anonymous method

Example

Anonymous methods provide a technique to pass a code block as a delegate parameter. They are methods with a body, but no name.

delegate int IntOp(int lhs, int rhs);

class Program
{
    static void Main(string[] args)
    {
        // C# 2.0 definition
        IntOp add = delegate(int lhs, int rhs)
        {
            return lhs + rhs;
        };

        // C# 3.0 definition
        IntOp mul = (lhs, rhs) =>
        {
            return lhs * rhs;
        };

        // C# 3.0 definition - shorthand
        IntOp sub = (lhs, rhs) => lhs - rhs;

        // Calling each method
        Console.WriteLine("2 + 3 = " + add(2, 3));
        Console.WriteLine("2 * 3 = " + mul(2, 3));
        Console.WriteLine("2 - 3 = " + sub(2, 3));
    }
}
