Yes, a DataContext returns
System.Data.Linq.Table<T>s (IQueryable<T>) orSystem.Data.Linq.ITables (IQueryable), so you can test whether your IQueryable instanceisone of these.Edit:
When a Linq operation (like
Select, orOrderBy) is applied to theIQuerablethe result is aSystem.Data.Linq.DataQuery. This is an internal type, so you cannot use theisoperator. In stead, doy.GetType().FullName.StartsWith("System.Data.Linq.DataQuery`1").
