powerpoint也一样，"System.Runtime.InteropServices.Marshal.ReleaseComObject(obj);"释放所有引用，最后System.GC.Collect();

object objmissing = System.Reflection.Missing.Value;Excel.ApplicationClass application = new ApplicationClass();Excel.Workbook book = application.Workbooks.Add(objmissing);Excel.Worksheet sheet = (Excel.Worksheet)book.Worksheets.Add（objmissing,objmissing,objmissing,objmissing);//操作过程 ^&%&×&……&%&&……//释放sheet.SaveAs(path,objmissing,objmissing,objmissing,objmissing,objmissing,objmissing,objmissing,objmissing);System.Runtime.InteropServices.Marshal.ReleaseComObject((object)sheet);System.Runtime.InteropServices.Marshal.ReleaseComObject((object)book);application.Quit();System.Runtime.InteropServices.Marshal.ReleaseComObject((object)application);System.GC.Collect();
