        if (datagridaddfield.Rows[i].Cells[1].Value != null)
        {
            bulkCopy.ColumnMappings.Add(datagridaddfield.Rows[i].Cells[0].Value.ToString(), datagridaddfield.Rows[i].Cells[1].Value.ToString());

i want program check this line if (datagridaddfield.Rows[i].Cells[1].Value != null) but program not checking!

The problem is that you are passing wrong parameters to ColumnMappings.Add . What you are doing now is passing cell values which doesn't make sense to Column mapping. One of the overloads should be passed the columns indexes to map. You could also use column names. Check out SqlBulkCopyColumnMappingCollection.Add Method .
