Question

Say I have a class named Frog, it looks like:

public class Frog {      public int Location { get; set; }      public int JumpCount { get; set; }        public void OnJump()      {          JumpCount++;      }  } 

I need help with 2 things:

1. I want to create an event named Jump in the class definition.
2. I want to create an instance of the Frog class, and then create another method that will be called when the Frog jumps.

Answer 1

public event EventHandler Jump; public void OnJump() {     EventHandler handler = Jump;     if (null != handler) handler(this, EventArgs.Empty); } 

then

Frog frog = new Frog(); frog.Jump += new EventHandler(yourMethod);  private void yourMethod(object s, EventArgs e) {      Console.WriteLine('Frog has Jumped!'); }
