using System;
// Declare delegate -- defines required signature:
delegate void SampleDelegate(string message);
class MainClass
{
// Regular method that matches signature:
static void SampleDelegateMethod(string message)
{
Console.WriteLine(message);
}
static void Main()
{
// Instantiate delegate with named method:
SampleDelegate d1 = SampleDelegateMethod;
// Instantiate delegate with anonymous method:
SampleDelegate d2 = delegate(string message)
{
Console.WriteLine(message);
};
// Invoke delegate d1:
d1("Hello");
// Invoke delegate d2:
d2(" World");
}
}
