Question

I learned that IQueryable or IEnumerable datatypes do not return the results at the first place and only return them when needed. However when I open that object in the watch inspector I saw all the objects are there.

Is there anything wrong in my code or it just showing because I had call it on the watch ?

[When I view the pendings object in the watch dialogbox I saw all the list items but it shouldn’t load at the first place. Is there anything wrong in my approaching or is it just showing because I had call it on the watch.]

 public IQueryable<PurchasePendingView> PurchasePendings() {
            var pendings = db.PurchasePendingViews
                             .Where(m => m.AccountStatusID != StructAccountStatus.Succeed); // when I view it in the watch dialougebox I saw all the list items but it shouldn't load at the first place. Is there anything wrong in my approaching or is it just showing because I had call it on the watch. 
            if (ApplicationEnvironment.DEBUGGING) {
                return pendings;
            } else if (IsMobileAccount()) {
                var showroom = db.ShowRooms.FirstOrDefault(m=> m.MemberID == employee.MemberID);
                if (showroom != null) {
                    return pendings.Where(m => m.ShowRoomID == showroom.ShowRoomID);
                } else {
                    return pendings.Where(m => m.CountryDivisionID == employee.CountryDivisionID);
                }
            } else { 
                //normal salary employee can see every detail
                return pendings;
            }
        }

Note: Currently my lazy loading is off.

The collections are evaluated the first time you iterate through the results.

Since you’re iterating through the results in the watch inspector, they are evalauated then.
