How do you use the LINQ to SQL designer to generate accessor methods for subclasses?
- by Pricey
Above is the LINQ to SQL designer view for my data context.
Below is the relevant code:
public System.Data.Linq.Table<ActivityBase> ActivityBases
{
get
{
return this.GetTable<ActivityBase>();
}
}
...
[Table(Name="dbo.Activities")]
[InheritanceMapping(Code="1", Type=typeof(ActivityBase), IsDefault=true)]
[InheritanceMapping(Code="2", Type=typeof(Project))]
[InheritanceMapping(Code="3", Type=typeof(ProjectActivity))]
[InheritanceMapping(Code="5", Type=typeof(Task))]
[InheritanceMapping(Code="4", Type=typeof(Activity))]
public abstract partial class ActivityBase : INotifyPropertyChanging, INotifyPropertyChanged
{
...
Is there a way to generate accessor methods for the subclasses as shown in the inheritance mapping above (Project, Task, etc...) without doing it manually? I added them manually but then a change in the designer overwrites any manual changes.
Am i doing this wrong? should I not be making accessors for the sub classes? filtering from ActivityBase seems worse to me.
Thanks for any help on this.
