You can't - a DataTable.Columns collection requires that all column Names must be unique. You can add a column with a different name but the same header text, or with a different mixture of upper and lower case characters, but the Name must be unique - otherwise it can't determine which one you mean!

ok.. thanks.. but pls tell me any other method to add column with same column name in another way not in datatable...

You probably can't - no collection which uses names will allow you to have to identical values - it would be like you having the same telephone number as me, and us both expecting only the calls for us to come through.
