Empty value in column data table

I have the DtOperacoes data table, in this table I have 8 columns. I need to know if the column 6 of the index contains the empty value, how could I do that? I tried to do it as follows: DtOperacoes.AsEnumerable.Where(function(x) x(6).ToString.Contains(“”)).Count>0
Is this correct? @Anil_G It already helped me last week in a similar doubt, but I couldn’t use the same topic

@Marilia_Gabriela_de

Please try this

DtOperacoes.AsEnumerable.Where(function(x) IsNothing(x(6)) OrElse String.IsNullOrEmpty(x(6).ToString.Trim)).Count>0

cheers
