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*

I know this has been properly answered but I'll include an example to show you the syntax to achieve what you want:

public class Person
{
    private 
    public string FirstName
    {
        get
        {
            return _firstName;
        }
        set
        {
            // see how we can call a method below? or any code for that matter..
            _firstName = SanitizeName(value);
        }
    }
}
