C# 如何在选定节点的子节点中获取某些字段。在C中

我以前知道怎么做，但现在我老了，老了。我有一个xml文件：

如何返回所选节点的子节点的UnitName列表

谢谢！请随便嘲笑我的秃头。

你应该和我一起去

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

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);
}

---

selectedNode.SelectNodes//UnitName；？它在unitName对象不包含“InnterText”定义时引发错误。。。我使用以下命令运行它：XmlNodeList nodes=MainWindow.SelectedNode.SelectNodes//UnitName；节点{MessageBox.Show中的foreach XmlNode unitName将删除以下单位：+unitName.InnerText；}

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);
}
