Events and delegates in C#

C# events are used to solve troubles in delegates. One of them can easily override delegate properties, which can eventually lead to bugs in your code. To avoid this, C# uses events and defines wrappers around delegates.

Events in C

#To use events, you should first define a delegate. An event is a delegate type, pressing a key is an example of an event.

public delegate voide Demo(String val);     
public event Test TestEvent;   

Events can hold delegates like this.

this.TestEvent += new Demo (DemoData);

Delegation in C

#A delegate is a reference type variable that holds a reference to a method. References can be changed at runtime.

public delegate void Demo(String val);
