保存现有word文档时出现问题
本文关键字：问题 word 保存 文档 | 更新日期: 2023-09-27 18:24:00
在C#中自动化word文档后，我正试图在桌面上保存一个现有的docx文件。我正在使用窗口窗体来执行我的应用程序。当桌面上不存在相同的文件名时，我可以保存文档。然而，当我再次尝试保存相同的文件名时，它会给我以下错误消息：
当文件被另一个进程使用时，无法保存。尝试使用新名称保存文件。（C:''Desktop''TempWord.docx）
我在微软网站上读到了，我可以使用SaveAs。如果有一个现有的文件名，它会自动覆盖它。
我不太确定为什么会出现这种消息，因为在运行该程序时，我根本没有打开任何其他word文档。
我不太确定如何解决这个问题。也许我做了一些我没有看到的非常愚蠢的事情：（
这是我的代码：

我不太确定我哪里做错了。
编辑：我把原始代码放在.
我用这个做了一个方法，所以把这行代码放在按钮generate中去掉，然后复制下面的新方法，这样你的新代码应该看起来像这个
