Im writing some service in C# and I have to use MongoDB.Driver 2.11.2. I have some issue when grouping my list of items. It looks like a bug. This is my code:
var totals = Collection.AsQueryable().GroupBy(s => s.StoreId, (key, group) => new Test { Key = key, LabOnHandTestCount = group.Count(groupItem => groupItem.IsLab.HasValue && groupItem.IsLab.Value), LabOnHandPrice = group.Where(groupItem => groupItem.IsLab.HasValue && groupItem.IsLabd.Value) .Sum(z => z.TotalCost), LabOnHandPrice2 = group.Sum(g=> g.IsLa.HasValue && g.IsLab.Value ? g.TotalCost:0), LabOnHandPrice3 = group.Where(gg => gg.IsLab.Value == true).Sum(s=>s.TotalCost), }).ToList();
I got different results from next lines.
- first line:
LabOnHandPrice = group.Where(groupItem => groupItem.IsLab.HasValue && groupItem.IsLabd.Value)
.Sum(z => z.TotalCost)
- second line(the right result):
LabOnHandPrice2 = group.Sum(g=> g.IsLa.HasValue && g.IsLab.Value ? g.TotalCost:0),
It looks like "Where" method of "first line" got ignored and calculation performed on wrong values. And also the result of the "first line" does not changes if i change a condition. I did not find any information on MongoDB official site.
Why "Where" method got ignored and i have different results? Is there any solution?
Tnx in advance.
