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

1. Change the access of the BooleanValue to private and only allow changing it through one method for consistency.

2. Fire your custom event in that method

.

private bool _boolValue;

public void ChangeValue(bool value)
{
    _boolValue = value;
   // Fire your event here
}

Option 2: Make it a property and fire the event in the setter

public bool BoolValue { get { ... }  set { _boolValue = value; //Fire Event } }

Edit: As others have said INotifyPropertyChanged is the .NET standard way to do this.
