Delegate and event in C#

A delegate is a type that safely encapsulates a method, similar to a function pointer in C and C++. Unlike C function pointers, delegates are object-oriented, type safe, and secure. The type of a delegate is defined by the name of the delegate.
An small example:

// Create a method for a delegate.
public static void DelegateMethod(string message)
{
    System.Console.WriteLine(message);
}

And now declare and just call..

// Instantiate the delegate.
Del handler = DelegateMethod;

// Call the delegate.
handler("Hello World");

Some scopes where delegates are used:
1. Event handlers (for GUI and more)
2. Starting threads
3. Callbacks (e.g. for async APIs)
4. LINQ and similar (List.Find etc)
5. Anywhere else where I want to effectively apply "template" code with some specialized logic inside (where the delegate provides the specialization)
