Excel工作表重命名将无法工作
我想重命名指定的工作表，并把一些处理的数据，但下面的代码（这看起来几乎相同，我可以find这个和其他网站上的每个例子）只是不会我想要的：
try { xl.Worksheet = (ExcelRefer.Worksheet) xl.Workbook.Worksheets.get_Item("Sheet1"); xl.Worksheet.Name = "Smoothed result"; xl.Workbook.Save(); xl.Range = xl.Worksheet.UsedRange; Debug.WriteLine("Saved"); } catch(Exception exception) { MessageBox.Show(exception.Message); } 这个exception永远不会抛出，所以代码不包含任何错误，但是我打开的文档中的工作表仍然具有相同的名称。 另外，
Debug.WriteLine(...)
方法被调用并且输出被正确显示。 当我告诉Workbook保存时，它甚至会问我是否要覆盖现有的文件。 谁能告诉我我做错了什么？
编辑：
xl是一个类的对象，它包含了使用excel的所有必要的元素。

当你完成后你有没有试过closuresExcel？
我不能完全弄清楚你从哪里gettng xl ，但是下面的代码适用于我：
Microsoft.Office.Interop.Excel.Application xlApp = new Microsoft.Office.Interop.Excel.Application(); Workbook book = xlApp.Workbooks.Open(@"C:\test.xlsx"); Worksheet xl = book.Worksheets.get_Item("sheet1"); xl.Name = "Smoothed result"; book.Save(); book.Close();
编辑
看到你用来打开工作簿的代码后，我认为问题就在那里。 您正在打开文件使用：
xl.Workbook = xl.App.Workbooks.Open(s, 0, true, 5, "", "", true, Microsoft.Office.Interop.Excel.XlPlatform.xlWindows, "\t", false, false, 0, true, 1, 0);
第三个参数是您已设置为true的ReadOnly参数。 尝试将其设置为false 。
