HI们创建一个XML文件并保存它，但是说另一个进程正在使用该文件，我怎么能杀死它？ [英] HI guys creating an XML file and saving it, but says file is in use by another process, how can I kill that?

问题描述

我是xml文件中的新手，所以我希望有人能说出我做错了什么以及出了什么问题。

我的尝试：



Google和rewritte .....和xmlwritter

解决方案

应用程序应该永远不会杀死任何其他进程。



当一个文件被另一个进程使用时显示相应的错误消息。然后，用户可以识别该进程以关闭该文件。 （可选）提供重试按钮和/或更改文件名的选项。



要获得打开文件的进程，可以使用过程资源管理器 [ ^ ]。

为什么不使用

I am a rookie in xml files, so i hope someone can tell what i am doing wrong and where is going wrong.

What I have tried:

Google and rewritte..... and xmlwritter

解决方案

An application should never kill any other process.

When a file is in use by another process show a corresponding error message. The user might then identify that process to close the file there. Optionally provide a Retry button and / or an option to change the file name.

To get the process that has opened the file you can use the Process Explorer[^].

Why don't you use

XmlDocument.Save()

?
