Question

I have the following linq:

     var wcd = dbContext.Programs.Where(p => p.Id == Id).ToList();
     dbContext.DeleteObject(wcd); 
     SaveChanges();

I get a message saying that I do not have a definition for DeleteObject in my Model.
I can though do SaveChanges(),etc.

I tried the following:

        var wcd = dbContext.Programs.Where(p => p.Id == Id).ToList();
        dbContext.Programs.Remove(wcd);   

but I get the following
The best overloaded method match for ‘System.Data.Entity.DbSet
.Remove has some invalid arguments

Answer 1

Is it a DbContext? If so you’re going to need to use Remove which is part of your DbSet:

EDIT:

You need to loop through your list and remove then individually:

foreach (var wc in wcd.ToList())
{
    dbContext.Programs.Remove(wc);
}
dbContext.SaveChanges();
