37.3k

In C#, an event handler is a delegate with a unique signature, as seen below. Vacant public delegate (object sender, MyEventArgs e); MyEventHandler (object sender, MyEventArgs e); The object that triggered the event is specified by the first parameter (sender) in the above declaration. The above declaration's second parameter (e) contains data that can be used in the event handler.

Events in C sharp can be categorized into three different types:

  • Events that execute code: These events execute a single statement or block of statements and then return control back to the calling function.
  • Event handlers: These events are called when something happens during the execution of a program. They generally perform one task and then return control back to the calling function.
  • Events that do not execute code: These events are used to handle exceptions that may occur during execution of a program.

Events can be used to trigger different actions such as playing a sound, displaying an image, updating a text string, or updating a value on a UI element. Events are useful when you want to respond to something that happens outside of your code.

The first example is a method that returns the value of a number. This method has two parameters, the value to be returned and the starting index. The starting index is an integer that starts at zero and increases by one with each iteration of the loop.

In this section, we will discuss the purpose of events in C sharp and how they can be used to organize your code. We will also discuss how to use them so that they do not get in the way of your code.
