给定一个选定的节点（保证是分区节点）：

selectedNode = (XmlNode)OOB.SelectedItem;

如何return selectedNode 的子节点的 UnitName 列表？

谢谢！请随意鄙视我的光头

Answer 1

你应该选择

var unitNames = selectedNode.SelectNodes(".//UnitName");
foreach(XmlElement unitName in unitNames)
{
    Console.WriteLine(unitName.InnerText);
}

Answer 2

试试这个：

XmlDocument doc = new XmlDocument();
doc.Load("sample.xml");

var divisions = doc.SelectNodes("//Division");
var firstDivision = divisions[0]; //your "SelectedItem"

XmlNodeList unitNames = firstDivision.SelectNodes("./Unit/UnitName");
foreach(XmlNode unitName in unitNames)
{
    Console.WriteLine(unitName.InnerText);
}
