I think the error actually explains the problem pretty well, doesn't it? You need to do NOT IN ('one, 'two', 'etc')

Cannot be sure with so little information, but I think that your problem is that you embed a variable name in a string, when you want to use the value of the variable.

C#

DataRow[] rows = dt.Select("CompanyID not in oCompanyBO.SelectedSupplierIDs");

should be

C#

DataRow[] rows = dt.Select(string.Format("CompanyID not in ({0})", oCompanyBO.SelectedSupplierIDs));

if oCompanyBO.SelectedSupplierIDs is a comma separated list.

However, if oCompanyBO.SelectedSupplierIDs is an array of SelectedSupplierID (int) then you need to first create a comma separated string

C#

string idList = string.Join(",", oCompanyBO.SelectedSupplierIDs);
DataRow[] rows = dt.Select(string.Format("CompanyID not in ({0})", idList));
