I have this command to select only the groups from a datatable:
' Group
loResult = loDataTable.AsEnumerable().GroupBy(Function(r) r.Field(Of Integer)(lcPrimaryKey)).[Select](Function(g) g.First()).CopyToDataTable
I just found out that this will generate an error if one of the values is a null.

Is there a way I can add support in this command for such situation?
