推荐答案

您需要深入研究内存映射文件:

祝你好运！

You need to dive into memory mapped files:

Good luck!

实际上，您的文件以独占模式打开.在编写器中，完成编写过程后，需要关闭XmlWriter(如果正在使用)对象.如果以只读模式打开xml，则不会看到错误消息.

因此，让我们知道您正在使用哪个类(XmlWriter，XmlReader，XDocument，XElement，.... ???)在xml中进行读写.然后我们可能会建议您解决方案.还要发布一些用于读取器和写入器应用程序的代码.

Hi,

Actually your file is open with exclusive mode. in your writer you need to close the XmlWriter(if you are using it.) object as and when you are done with the writing process. if you open xml with readonly mode then you will not see the error message.

So, let us know which class(XmlWriter, XmlReader, XDocument, XElement, ....???) you are using for reading and writing in the xml.then we may suggest you the solution. Also post some of the code for reader and writer application.

Thanks
