Question

I have some objects which have been created automatically by linq2SQL.

I would like to write some code which should be run whenever the properties on these objects are read or changed.

Can I use typical get { //code } and set {//code } in my partial class file to add this functionality? Currently I get an error about this member already being defined.

This all makes sense.

Is it correct that I will have to create a method to function as the entry point for this functionality, as I cannot redefine the get and set methods for this property.

I was hoping to just update the get and set, as this would mean I wouldn’t have to change all the reference points in my app. But I think I may just have to update it everywhere.

Not sure about read, but you could track changes of your objects. E.g. there is PropertyChangedEventHandler on auto generated entities.

So what have you do is to white a partial class (let’s assuming you have a Person entity):

public partial class Person
{
    public Person()
    {
        this.PropertyChanged += 
           new PropertyChangedEventHandler(Person_PropertyChanged);
    }

    protected void Person_PropertyChanged(object sender, PropertyChangedEventArgs e)
    {
        // your code here
    }
}
