Callbacks, events, and anonymous methods
Callbacks are a pivotal concept in asynchronous and event-driven programming. They are essentially delegates that point to a method, allowing it to be called at a later time. This facilitates non-blocking code execution, crucial for responsive applications.
Imagine a book publishing system where we need to perform actions such as sending notifications after a book is published. Here, a callback can notify other parts of the system once the publishing process is completed:
public delegate void BookPublishedCallback(string bookTitle);
public class BookPublishingManager
{
public void PublishBook(string bookTitle, BookPublishedCallback callback)
{
// Book publishing logic here...
callback(bookTitle);
}
}
// Usage
BookPublishingManager manager = new BookPublishingManager();
manager...
