Question

Im want to delete rows from a table that in my data base.
i have the member

private static WeightScaleEntities Weight = new Weight();

this member contains my database. in the data base i have table: User_Activity.

I want to delete rows from user activity by given i_UserActivityId, as follow:

//Get the rows for delete
var deleteUserActivities = from details in Weight.User_Activity
                                   where details.Id == i_UserActivityId
                                   select details;

Now i want to delete this rows, so i tried to do:

foreach (var item in deleteUserActivities)
{
         m_WeightScaleEntities.User_Activity.*
}

and i dont get the method DeleteOnSubmit!

Why?
there is another option???

Answer 1

User_Activity.*: is that a typo?

What I think you want is:

foreach (var item in deleteUserActivities)
{
     Weight.DeleteObject(item);
}

And then SaveChanges() on the object context.

BTW, a static object context is not a good idea. You should carefully control the life cycle of object contexts.
