Excel In C#

在项目中需要导入Excel文件，其中需要把Excel格式的数据转换为我们私有格式。

因此需要测试尽可能多的负数，于是乎写了如下的code进行测试：

public void ExcelLoadSave(int targetValue,string fileName)
        {
            Excel._Application app = new Excel.Application();
            app.Visible = false;
            Excel.Workbooks wookbooks = app.Workbooks;
            Excel._Workbook workbook = app.Workbooks.Open(fileName, Excel.XlUpdateLinks.xlUpdateLinksUserSetting, false, 5, "", "", false, Excel.XlPlatform.xlWindows, "", true, false, true, false, true, Excel.XlCorruptLoad.xlNormalLoad);
            Excel._Workbook wookbook = wookbooks.get_Item(1);
            Excel.Sheets sheets = wookbook.Sheets;
            Excel._Worksheet ExcelSheet = (Excel.Worksheet)sheets.get_Item(1);
            Excel.Range CellRange = (Excel.Range)ExcelSheet.Cells[1, 1];
            CellRange.Value2 = targetValue;
            workbook.Save();
            wookbook.Close(false, Missing.Value, Missing.Value);
            app.Quit();

            KillExcelProcess();

        }

        private void KillExcelProcess()
        {
            Process[] pss = Process.GetProcesses();
            for (int i = 0; i < pss.Length; i++)
            {
                if (pss[i].ProcessName == "EXCEL.EXE")
                {
                    pss[i].Kill();
                }
            }
        }
