如何在ASP.NET中处置或关闭XML Document的实例

Question

有一个问题，其中XML Document.Save导致进程无法访问该文件的错误，因为它正被另一个进程或语句使用无效的XML文档。我认为这是因为我没有处置XML Document对象在它的操作完成后。是否可以这样做。有解决方法吗？

Answer 1

It depends on which overload of the Save method you are using. If you pass directly a filename as string there shouldn't be issues. If you pass a stream or xmlwriter you need to ensure that it is properly disposed:

using (Stream stream = ...)
{
    doc.Save(stream);
}

Answer 2

XmlDocument, as well as the newer XDocument, are in-memory representations of an XML document, so you don't need to close them.

Perhaps you are using an underlying Stream or similar to read the documents, and that is what needs to be closed ? Without more context, it is almost impossible to answer.
