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()? 这篇关于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？的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
