先对COM组件的引用"Microsoft Excel 11.0 Object Libarary" -->系统中的Office 的不同可能版上有点不同.
Excel.Application ExcelIRS; //Excel 文档的主程序( 可以打开多个工作薄)
Excel.Workbook RSbook;      //工作薄
Excel.Worksheet thisWorkBookSheet; //表单


新建
 RSbook=(Excel.Workbook)ExcelIRS.Application.Workbooks.Add(Missing.Value);
得到工作表
thisWorkBookSheet = (Excel.Worksheet)RSbook.ActiveSheet;

输入
Excel.Range rg = (Excel.Range)thisWorkBookSheet.get_Range(thisWorkBookSheet.Cells[i, j], thisWorkBookSheet.Cells[i+cellsValue.GetLength(0)-1,j+cellsValue.GetLength(1)-1]);
            rg.Value2 = cellsValue;

保存
 work.SaveAs(filePath, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Excel.XlSaveAsAccessMode.xlNoChange, Missing.Value, Missing.Value, Missing.Value, Missing.Value, Missing.Value);

退出
 RSbook = null;
                ExcelIRS.Workbooks.Close();
                ExcelIRS.Application.Quit();
                ExcelIRS.Quit();

大概这是这么一些方些,只提供方向哦,网上好多详细操作...
