XPathDocument何时实际加载文件？ [英] When does XPathDocument load the file actually?

问题描述

string filename =" myFile.xml" ;;

XPathDocument xpd = new XPathDocument（filename）;

XPathNavigator xpn = xpd.CreateNavigator（）;

你知道XPathDocument何时真正将xml文件加载到内存中吗？

Do you know when XPathDocument really loads the xml file to the memory?

创建对象时，或创建导航器时，还是任何其他时间？

When creating the object, or when creating the navigator, or any other time?

我想放在Cache对象中加载文档的过程，但是当对象出现时已创建，它不会将文档加载到其内存中。

I want to put the process of loading the document in Cache object, but it seems when the object is created, it doesn't load the document in its memory.

非常感谢任何有用的想法。

Any useful thoughts is highly appreciated.
