xml和TreeView

 1。TreeView代码代码：

 1 private void Form1_Load(object sender, EventArgs e)
 2 {<br>                   //代码为TreeView添加子项
 3     treeView1.ContextMenuStrip = contextMenuStrip1;
 4     TreeNode tn = new TreeNode("默认");
 5     
 6     treeView1.Nodes.Add(tn);
 7  
 8 }
 9  
10 private void button1_Click(object sender, EventArgs e)
11 {<br>                  //代码为TreeView添加子项
12     string text = textBox1.Text;
13     TreeNode tn = new TreeNode(text);
14     TreeNode tr = treeView1.SelectedNode;
15     tr.Nodes.Add(tn);
16  
17 }
18  
19 private void 删除ToolStripMenuItem_Click(object sender, EventArgs e)
20 {<br>                      //删除选中项
21     treeView1.SelectedNode.Remove();
22 }

76                           break;
