@supermanPunch hi, can help on this? tq very much!!


If I understand your requirement correctly, the following will work. Can you check this?

dict = dtInputName.AsEnumerable.ToDictionary(Function(r) r("OrderNo").ToString,Function(r) Int32.Parse(r("Quanitity").ToString))
dtResult = dtInput.AsEnumerable.GroupBy(Function(r) r("OrderNo").ToString).SelectMany(Function(g) g.Take(dict(g.Key))).CopyToDataTable (10.3 KB)


hi, sorry for late reply,
Thank your for the help,
Unfortunately the solution doesnt cover this type of input:
Assume:ET466245 quantity is 2.
My expected output should be like this:

Only the blank SID that need to be remove for matched order no


Can you elaborate regarding difference between ET466244 case and ET466245case?



for ET466244, i only need to remove 3 blank rows cause total quantity is 5 but blanks rows is 8.
for ET466245, i need to remove 1 blank row cause total quantity is 2 but blanks rows is 3


Thanks for sharing. Probably the following will work. Can you try this?

dtResult = dtInput.AsEnumerable.GroupBy(Function(r) r("OrderNo").ToString).SelectMany(Function(g) g.GroupBy(Function(r) r("SID").ToString).SelectMany(Function(g2) if(String.IsNullOrEmpty(g2.Key),g2.Take(dict(g.Key)),g2))).CopyToDataTable() (10.7 KB)


tq so much!
