            System.Xml.XmlDocument doc = new System.Xml.XmlDocument();
            doc.LoadXml(xml);
            //Console.WriteLine("totalCount : " + doc.GetElementsByTagName("totalCount")[0].FirstChild.Value);
            textBox1.Text = "total:"+doc.GetElementsByTagName("totalCount")[0].FirstChild.Value+"\r\n";
            foreach (System.Xml.XmlNode node in doc.GetElementsByTagName("DeliverMessage"))
            {
                textBox1.Text = textBox1.Text + "id:" + node["Id"].FirstChild.Value + "\r\n";
                textBox1.Text = textBox1.Text + "Userid:" + node["Userid"].FirstChild.Value + "\r\n";

Answer 2

using System;
using System.Windows.Forms;
using System.Xml;namespace xmlNode
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }        private void button1_Click(object sender, EventArgs e)
        {
            XmlDocument xmldoc = new XmlDocument();
            xmldoc.Load("1.xml");
            XmlNode xn = xmldoc.SelectSingleNode("items/rtnCode");
            string s = xn.InnerText;
        }
    }
}s就是 你要的值  你再根据这个值判断 执行啥子

Answer 3

XmlDocument doc=new XmlDocument("");
doc.Load("");
XmlNode node=doc.SelectSingleNode("//rtnCode");
if(node!=null){}

Answer 4

XmlNode node=XmlDocment.SelectSingleNode("//itmes//rtncode");

Answer 5

XmlDocument xmldoc = new XmlDocument();
            xmldoc.Load("xml路径");
            XmlNode node= xmldoc.SelectSingleNode("//rtnCode");
            if(node!=null)
            string s = node.InnerText;
