Question

I have a table in my LINQ2SQL diagram with a column called DayOfWeek in table JourneyBooking. The designer.cs has the definition of this as:

[Column(Storage="_DayOfWeek", DbType="TinyInt NOT NULL")]
public int DayOfWeek
{
    get
    {
        return this._DayOfWeek;
    }
    set
    {
        if ((this._DayOfWeek != value))
        {
            this.OnDayOfWeekChanging(value);
            this.SendPropertyChanging();
            this._DayOfWeek = value;
            this.SendPropertyChanged("DayOfWeek");
            this.OnDayOfWeekChanged();
        }
    }
}

I have a partial class for the JourneyBooking class. Is it possible to extend/overwrite the above DayOfWeek property with my own property?

The issue I am having is that DayOfWeek is 0-6 in C# but 1-7 in SQL, so I was thinking that I could overwrite the DayOfWeek property to subtract or add 1 depending on whether it was a get or set, is this possible or would I need to re-write all of the above code in my partial class?

You could much more easily write another property in your partial that just references this one in it’s get/set, then just use that property in your code. For example I’d rename the generated one for SQL to something like DayOfWeekStorage or DayOfWeekSQL and then do this in the partial:

public int DayOfWeek
{
    get { return DayOfWeekStorage -1; }
    set { DayOfWeekStorage = value + 1; }
}
