Hi,
If you want to get the most occurrence values in a column, the following will help you.
Value
dt.AsEnumerable.GroupBy(Function(r) r("ColumnName").ToString).OrderBy(Function(g) g.Count).Last().First().Item("ColumnName").ToString()
Count
dt.AsEnumerable.GroupBy(Function(r) r("ColumnName").ToString).OrderBy(Function(g) g.Count).Last().Count
Regards,
