//C# Event using Action delegate:

public event Action OnSomeEvent;
public event Action<string> OnSomeEventWithParameters;

// Rising the event, must check if is null:
void SomeMethod()

//Next
int i = (i+1) % targetArray.Count

//Prev

//C# Delegate:
 
public delegate [return] DelegateName([type parameter]...);
 
//Sample:
public delegate void CalbackHandler(int pIndex);
 
//So you can use it as a parameter to other method:
public void PassDelegateByParameter( CallbackHandler pHandler )
