Is there a way to intercept setters and getters in C#?

Question

In both Ruby and PHP (and I guess other languages as well) there are some utility methods that are called whenever a property is set. ( *instance_variable_set*

Answer 1

Not out of the box. You would need to insert code into each properties setter and getter, either manually or automatically using IL rewriting.

When you want to do it manually, you can't use automatic properties any more.
When you want to do it automatically, have a look at AOP.
