C# Event Handler: Purpose Explained

In C#, an event handler is a delegate type used for handling events. It defines the signature of the event handling method to be called when the event occurs. An event handler allows developers to attach event handling methods to events, in order to execute specific operations when the event happens.

Event handlers can be used to manage a variety of events such as button clicks, mouse movements, and keyboard inputs on the user interface. When an event occurs, the event handling method will be automatically called to execute the corresponding logical code.

Using event handlers, developers can implement an event-driven programming model, making the code more readable and maintainable. It simplifies and improves communication between different components, while also providing greater flexibility and scalability.
