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

It is possible to do directly in the property body itself, but then you need to use a proper backing field instead of auto-implemented properties.

private string firstName;

public string FirstName 
{ 
  get { return firstName;} 
  set 
  {
    if(check(value))
    {
       firstName = value;
    }
  } 
}

Even with auto-implemented properties you get a backing field - this is generated by the compiler and you don't have direct access to it.

Edit:

Seeing as you don't want a backing field, you have other options - using an AOP tool such as PostSharp could help with that.
