I've recently started experimenting with PostSharp and I found a particularly helpful aspect to automate implementation of INotifyPropertyChanged. You can see the example here. The basic functionality is excellent (all properties will be notified), but there are cases where I might want to suppress notification.
For instance, I might know that a particular property is set once in the constructor and will never change again. As such, there is no need to emit the code for NotifyPropertyChanged. The overhead is minimal when classes are not frequently instantiated and I can prevent the problem by switching from an automatically generated property to a field-backed property and writing to the field. However, as I'm learning this new tool, it would be helpful to know if there is a way to tag a property with an attribute to suppress the code generation. I'd like to be able to do something like this:
[NotifyPropertyChanged]
public class MyClass
{
public double SomeValue { get; set; }
public double ModifiedValue { get; private set; }
[SuppressNotify]
public double OnlySetOnce { get; private set; }
public MyClass()
{
OnlySetOnce = 1.0;
}
}
