Question

I have to check if a column exists in a table, if it does than I have to delete it and if it doesn’t exist I have to add it, and only in vb.

I’ve read something about DataColumnCollection.Contains– for checking if the column exists, but I don’t really understand how to use it. any help is useful.

Answer 1

To remove it from the DataTable, first check whether it exists with Contains and then use Remove Try:

If myDataTable.Columns.Contains("columnName") Then
    myDataTable.Columns.Remove("columnName");
End If
