Create an event to watch for a change of variable

Question

Let\'s just say that I have:

public Boolean booleanValue;

public bool someMethod(string value)
{
   // Do some work in here.
   return booleanValue = true;
         


        

Answer 1

CallingClass.BoolChangeEvent += new Action(AddressOfFunction);

In your class with the bool property procedure:

public event Action BoolChangeEvent;
public Boolean booleanValue;
public bool someMethod(string value)
{
   // Raise event to signify the bool value has been set.
   BoolChangeEvent(value);

   // Do some work in here.
   booleanValue = true;
   return booleanValue;
}
