在Excel中，行和列实际上仍然是Range，只不过取得行和列的方法和前面几篇随笔出现的有点不同，要使用Worksheet的Rows和Columns属性的get_Item方法，下面是例子代码，演示了怎样选中行，并且在行之间复制数据，和插入行：
ThisApplication = new Excel.Application();
ThisWorkbook = ThisApplication.Workbooks.Open("z://Book1.xls", Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing, Type.Missing);
ThisApplication.DisplayAlerts = false;
xlSheet = (Excel.Worksheet)ThisWorkbook.Worksheets.get_Item(1);
//Excel.Range range = xlSheet.get_Range("G4",Type.Missing);
Excel.Range range = (Excel.Range)xlSheet.Rows.get_Item(18, Type.Missing);
Excel.Range range1 = (Excel.Range)xlSheet.Rows.get_Item(19, Type.Missing);
range.Value = "123";
range.Copy(range1);
range1.Rows.Insert(XlInsertShiftDirection.xlShiftDown);
ThisWorkbook.SaveAs("z://Book2.xls", Type.Missing, Type.Missing,
Type.Missing, Type.Missing, Type.Missing, Excel.XlSaveAsAccessMode.xlNoChange,
Type.Missing, Type.Missing, Type.Missing, Type.Missing);
关于Excel进程的释放，前面几篇随笔已经有了，这里就不再重复了。
