将要读取的是smoke下floortype中的value值，xml如下

  <?xml version="1.0" encoding="UTF-8" ?> - <PropDataBucket name="navisworks_df_floor_cicle" version="1.0">- <PropDataRow name="smoke" index="0" type="custom">- <target name="properties">  <property name="floortype" value="circular" />   <property name="length" value="" />   </target>  </PropDataRow>- <PropDataRow name="navisworks_df_floor_rectangular_01" index="1" type="">- <target name="properties">  <property name="floortype" value="rectangular" />   <property name="length" value="1000.00" />   </target>  </PropDataRow>  </PropDataBucket>

c#代码

using System;using System.Collections.Generic;using System.ComponentModel;using System.Data;using System.Drawing;using System.Linq;using System.Text;using System.Windows.Forms;using System.Xml;namespace WindowsFormsApplication1{    public partial class Form1 : Form    {        public Form1()        {            InitializeComponent();        }        private void Form1_Load(object sender, EventArgs e)        {        }        private void button1_Click(object sender, EventArgs e)        {                        string str = "";            XmlDocument doc = new XmlDocument();            doc.Load(@"e:\test.xml");//读入xml，注意@            XmlNode node = doc.SelectSingleNode("//PropDataBucket/PropDataRow[@name='smoke']//property[@name='floortype']");//设置节点位置            if (node != null)            {                             str = node.Attributes["value"].Value;//节点下多个数值名称的选择            }                      textBox1.Text = str;                  }    }}

效果如图
