C＃ – 以编程方式打开和closuresexcel文件的正确方法

我似乎无法find打开和closuresExcel文件的正确方法。

这是我必须打开我的文件，我觉得这太复杂了：

Microsoft.Office.Interop.Excel.Application excelApp = new Microsoft.Office.Interop.Excel.Application(); Microsoft.Office.Interop.Excel.Workbook excelWorkbook = excelApp.Workbooks.Open(workbookPath, 0, false, 5, "", "", false, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "", true, false, 0, true, false, false); Microsoft.Office.Interop.Excel.Sheets excelSheets = excelWorkbook.Worksheets; Worksheet sheet = (Microsoft.Office.Interop.Excel.Worksheet)excelApp.Worksheets[2]; sheet.Select(Type.Missing); 

我不知道如何正确closures它。 我需要用相同的path保存它，并确保在closures后，excel仍然不在后台运行。

有人可以让我容易吗？ 谢谢

半伪代码：

 using Excel = Microsoft.Office.Interop.Excel; # declare the application object Excel.Application xl = new Excel.Application(); # open a file Excel.Workbook wb = xl.Workbooks.Open("some_file.xlsx"); # do stuff .... # close the file wb.Close(); # close the application and release resources xl.Quit(); 

Answer 2

完成时释放COM对象…

 using Excel = Microsoft.Office.Interop.Excel; using System.Runtime.InteropServices; # declare the application object var xl = new Excel.Application(); # open a file var wb = xl.Workbooks.Open("some_file.xlsx"); # close the file wb.Close(); # close the application and release resources xl.Quit(); #release the COM objects created as a final step: Marshal.ReleaseComObject(wb); Marshal.ReleaseComObject(xl);
