项目类图：

 存储街道数据类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Street_Management_System
{
public class Street
{
public Street()
{
}

public Street(string streets, string jwh, string dong, string s)
{
Streets = streets;
Jwh = jwh;
Dong = dong;
S = s;
}

//街道
public string Streets { get; set; }
//居委会
public string Jwh { get; set; }
//楼房（栋）
public string Dong { get; set; }

//厅室
public string S { get; set; }
}
}

读取XML类：

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Xml;

namespace Street_Management_System
{
public class ReadXML
{
public ReadXML()
{
dic = new Dictionary<string, Street>();
}

public ReadXML(Dictionary<string, Street> dic)
{
this.dic = dic;
}

//存储xml文件的双列集合
public Dictionary<string, Street> dic { get; set; }

public Dictionary<string, Street> Read()
{
XmlDocument doc = new XmlDocument();
/*
* 读取xml文件
* */
doc.Load("Address.xml");
//获取xml文件的根节点
XmlNode xml = doc.DocumentElement;

/*
* 解析xml文件的各个接点并存入集合
* */
foreach (XmlNode item in xml.ChildNodes)
{
string street = item.ParentNode.Attributes["name"].InnerText;
string jwh = item.Attributes["name"].InnerText;
string dong = null;
string s = null;
foreach (XmlNode items in item.ChildNodes)
{
dong = items.Attributes["name"].InnerText;
foreach (XmlNode itemss in items.ChildNodes)
{
s = itemss.InnerText;
Street aaa = new Street(street,jwh,dong,s);
dic.Add(dong+"|"+s,aaa);
}
}
}
return dic;
}
}
}

主窗体类：

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;

/*
*拆解集合中的数据并赋值到TreeView控件的相应接点中
* */

}

private void tvStreet_AfterSelect(object sender, TreeViewEventArgs e)
