A Delegate is a reference to a function, in the same way that a TextBox variable is a reference to teh instance of a TextBox that appears on the screen. They are surprisingly handy: you can use them to write code that can work to a variety of destinations without changing the code. For example, you could write a Print method that took a delegate: Hide Copy Code private void DoPrint() { string text = "hello world!"; Print(text, PrintConsole); Print(text, PrintTextbox); } private void PrintConsole(string s) { Console.WriteLine("Console: " + s); } private void PrintTextbox(string s) { myTextBox.Text = "TextBox: " + s; } private delegate void printDestination(string s); private void Print(string s, printDestination pd) { pd("From Print: " + s); } You can completely change what happens to the text without changing the code in the Print method. There are a lot of other uses, but that's the general idea.
