XDocument xdoc = XDocument.Parse(xml);
foreach (XElement element in xdoc.Descendants("nationalList"))
{
   MessageBox.Show(element.ToString());
}

我想在 nationalList 通过每一个节点重复，但它不工作对我来说，它跳过了的foreach 环路完全。我在做什么错在这里？

I'd like to iterate through every nodes under nationalList but it isn't working for me, it skips the foreach loop entirely. What am I doing wrong here?

推荐答案

你不包括命名空间，这是http://www.lge.com/ddc，从父元素默认：

You're not including the namespace, which is "http://www.lge.com/ddc", defaulted from the parent element:

XNamespace ns = "http://www.lge.com/ddc";
foreach (XElement element in xdoc.Descendants(ns + "nationalList")
