Example 6: Basic Delegate Usage (_06DemoDelegate)

What it demonstrates:

This example shows the fundamental concept of delegates in C#.

Key Components:

• Delegate Declaration: delegate bool MyDelegate(int i);
  • Defines a delegate type that can point to methods returning bool and taking an int parameter
• Method Assignment: MyDelegate pointer = new MyDelegate(Check);
  • Creates a delegate instance pointing to the Check method
• Delegate Invocation: bool result = pointer(20);
  • Calls the method through the delegate

How it works:

1. Instead of calling Check(20) directly, we create a delegate pointer
2. The delegate acts as a "function pointer" that can invoke the Check method
3. When pointer(20) is called, it executes Check(20) and returns true (since 20 > 10)

Output:

True

Example 7: Delegate Parameter Passing (_07Demo)

What it demonstrates:

This shows how delegates can be passed as parameters to enable loose coupling between classes.
