I know how to write single cell into excel but when im trying it on array excel sheet is filling with only last value

this is my range

Excel.Range ServiceName = (Excel.Range)_sheet.get_Range(_sheet.Cells[38, "B"] as Excel.Range, _sheet.Cells[45, "B"] as Excel.Range);

_ServiceName is List which contains 1,2,3,4,5,6

for (int i = 0; i < _ServiceName.Count; i++)
            {
                ServiceNameArray[0, i] = _ServiceName[i];

            }

this i my trying to write into excel but as i said it there is only last item (6) in excel book

for (int i = 0; i < _ServiceName.Count; i++)
           {
               ServiceName.set_Value(Type.Missing, ServiceNameArray[0,i]);
           }
