写一个小程序

具体效果如下

第一步建类

Aderss类

public class Address   {       private string street;//街道       private string jwh;//居委会       private string floornum;//楼号          public string Street       {           get { return street; }           set { street = value; }       }       public string Jwh       {           get { return jwh; }           set { jwh = value; }       }       public string Floornum       {           get { return floornum; }           set { floornum = value; }       }         }

Commom类(主要用于解析XML文件)

public class Common    {        //解析XML文件，并且将解析的Xml文件内容加载到集合中      //public   List
 list=new List
();  key：       public  Dictionary
       
         list=new Dictionary
        
         ();        public  void ReadDataFromXML()        {           XmlDocument doc=new XmlDocument();           doc.Load("Address.xml");           XmlNode root = doc.DocumentElement;           foreach (XmlNode item in root.ChildNodes)           {               //创建一个地址对象               //Address address=new Address();               //address.Street = root.Attributes["name"].InnerText;               //address.Jwh = item.Attributes["name"].InnerText;              string street = root.Attributes["name"].InnerText;              string jwh= item.Attributes["name"].InnerText;               foreach (XmlNode child in item.ChildNodes)               {                   string floornum = child.Attributes["name"].InnerText;                   foreach (XmlNode node in child.ChildNodes)//child代表的是楼号，一个楼层上有多个房间                   {                       //每一个node都是一个房间                       Address address = new Address();                       address.Street = street;                       address.Jwh = jwh;                       address.Floornum = floornum;                       RoomAddress roomAddress=new RoomAddress();                       //RoomAddress类中才能反映出当前房间的具体位置信息                       //包括房间号，所在楼层，所在的校区，所在的街道                       //华清嘉园    B 1005  101                       //羊城花园  +A1004    101                       roomAddress.Roomnum =node.InnerText;                       roomAddress.Address = address;                       list.Add(address.Jwh+address.Floornum + roomAddress.Roomnum, roomAddress);                                          }               }                         }        }    }
        
       

RoomAdress类

public class RoomAddress   {       public RoomAddress()       {           address=new Address();       }       private string roomnum;       private Address address;       public string Roomnum       {           get { return roomnum; }           set { roomnum = value; }       }       public Address Address       {           get { return address; }           set { address = value; }       }   }

在主主窗体创建方法用于调用XML文件并且与Treeview绑定

common.ReadDataFromXML();            TreeNode root=new TreeNode();            root.Text = "石牌街道";            tvShow.Nodes.Add(root);            string jwh= "";            TreeNode tn = null;            TreeNode tnfloor = null;            string floor = "";            TreeNode child = null;            foreach (RoomAddress address in common.list.Values)//RoomAddress            {                if (floor != address.Address.Floornum)                {                    if (jwh != address.Address.Jwh)                    {                        tn = new TreeNode();                        tn.Text = address.Address.Jwh;                        root.Nodes.Add(tn);                    }                    tnfloor = new TreeNode();                    tnfloor.Text = address.Address.Floornum;                    tn.Nodes.Add(tnfloor);                }                child = new TreeNode();                child.Text = address.Roomnum;                tnfloor.Nodes.Add(child);                jwh = address.Address.Jwh;                floor = address.Address.Floornum;                     }

TreeView的选中事件并且将将节点上的文字赋值到TextBox控件上

//获取当前选中的节点            TreeNode selectNode = tvShow.SelectedNode;            if (selectNode!=null&&selectNode.Level==3)            {                string parentText = selectNode.Parent.Text;                string parentandparentText = selectNode.Parent.Parent.Text;                string treeText = parentandparentText + parentText + selectNode.Text;                txtJWH.Text = common.list[treeText].Address.Jwh;                txtStreet.Text = common.list[treeText].Address.Street;                txtRoomNum.Text = common.list[treeText].Roomnum;                txtFloor.Text = common.list[treeText].Address.Floornum;            }

这个小程序还有很多不足
