xml和TreeView

1。TreeView代码代码：

 private void Form1_Load(object sender, EventArgs e)
 {<br>                   //代码为TreeView添加子项
     treeView1.ContextMenuStrip = contextMenuStrip1;
     TreeNode tn = new TreeNode("默认");

     treeView1.Nodes.Add(tn);

 }

 private void button1_Click(object sender, EventArgs e)
 {<br>                  //代码为TreeView添加子项
     string text = textBox1.Text;
     TreeNode tn = new TreeNode(text);
     TreeNode tr = treeView1.SelectedNode;
     tr.Nodes.Add(tn);

 }

 private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)
 {<br>                      //删除选中项
     treeView1.SelectedNode.Remove();
 }

2.XML基本用法

 <?xml version="1.0" encoding="utf-8" ?>
 <Computers>

 <Computer typr="">

   <Name>LenovoY460</Name>

   <Price></Price>
   <CPU>酷睿i3</CPU>

 </Computer>

   <Computer typr="">

     <Name>Dell</Name>

     <Price></Price>
     <CPU>酷睿i7</CPU>

   </Computer>

 </Computers>

               //foreach (XmlNode item1 in item.ChildNodes) {

                   switch (item1.Name) {

                      case "Name":
                         Console.WriteLine("电脑的名字是：" + item1.InnerText);
                           break;
                       case "Price":
                          Console.WriteLine("电脑的价格是：" + item1.InnerText);
                          break;
                       case "CPU":
                             Console.WriteLine("电脑的CPU是：" + item1.InnerText);
                           break;

                  }

               }
               Console.WriteLine(item.Attributes["typr"].Value);
               Console.WriteLine("电脑的名字是：" + item["Name"].InnerText);
               Console.WriteLine("电脑的Price是：" + item["Price"].InnerText);
               Console.WriteLine("电脑的CPU是：" + item["CPU"].InnerText);
           }
           Console.ReadKey();
