Hi @RENU_KHALKHO

can you try this

Dt_Data.AsEnumerable.Sum(Function(su) If(Int32.TryParse(su(IndexOrColumnName).ToString.Trim, New Int32),Int32.Parse(su(IndexOrColumnName).ToString.Trim),0))

Thanks

Hi,

FYI, another solution:

dt.AsEnumerable.Where(Function(r) Double.TryParse(r("Amount").ToString,New Double)).Sum(function(r) Double.Parse(r("Amount").ToString))
