You can use PasteSpecial with xlPasteFormats.
xlPasteFormats
Excel.Range R1 = (Excel.Range)oSheet.Cells[11, 11]; R1.Copy(Type.Missing); Excel.Range R2 = (Excel.Range)oSheet.Cells[15, 15]; R2.PasteSpecial(Excel.XlPasteType.xlPasteFormats, Excel.XlPasteSpecialOperation.xlPasteSpecialOperationNone, false, false);
