如何从MachineEntrys中将uuid和src从此xml中获取到数组？ .net 4.5

我试过了，因为数组是空的：

**请勿编辑此文件。 **如果您在任何VirtualBox相关应用程序中对此文件进行更改 **正在运行，您的更改将在稍后被覆盖，而不会生效。 **使用VBoxManage或VirtualBox Manager GUI进行更改。

    <?xml version="1.0"?>
<!--
** DO NOT EDIT THIS FILE.
** If you make changes to this file while any VirtualBox related application
** is running, your changes will be overwritten later, without taking effect.
** Use VBoxManage or the VirtualBox Manager GUI to make changes.

您忽略了XML命名空间。你可以试试：

XmlNodeList nodes  = doc.DocumentElement.SelectNodes("//*[local-name()='MachineEntry']");

（如果需要，使用local-name（）函数展开其他级别）

如何在c＃中读取此XML中的数据？
