在C#的WinForm中增加一个treeView1控件
时间：2010-09-02 来源：花田错
使用TreeNode的tag属性放置编码，TreeNode的Text属性放置名称，最简单的示例如下——先添加两个节点，然后处理AfterSelect事件：
using System;
using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data;
namespace testtree
{
/// <summary>
/// Form1 的摘要说明。
/// </summary>
public class Form1 : System.Windows.Forms.Form
{
private System.Windows.Forms.TreeView treeView1;
/// <summary>
/// 必需的设计器变量。
/// </summary>
private System.ComponentModel.Container components = null;
public Form1()
{
//
// Windows窗体设计器支持所必需的
//
InitializeComponent();
//
// TODO:在InitializeComponent调用后添加任何构造函数代码
//
TreeNode tn = new TreeNode();
tn.Tag = "1001"; tn.Text = "hello";
TreeNode tn2 = new TreeNode();
tn2.Tag = "1002"; tn2.Text = "ok";
tn.Nodes.Add(tn2);
treeView1.Nodes.Add(tn);
}
/// <summary>
/// 清理所有正在使用的资源。
/// </summary>
protected override void Dispose( bool disposing )
{
if( disposing )
{
if (components != null)
{
components.Dispose();
}
}
base.Dispose( disposing );
}
#region Windows窗体设计器生成的代码
/// <summary>
///设计器支持所需的方法-不要使用代码编辑器修改
/// 此方法的内容。
/// </summary>
private void InitializeComponent()
{
this.treeView1 = new System.Windows.Forms.TreeView(); this.SuspendLayout();
//
// treeView1
//
this.treeView1.ImageIndex = -1; this.treeView1.Location = new System.Drawing.Point(16, 8); this.treeView1.Name = "treeView1"; this.treeView1.SelectedImageIndex = -1; this.treeView1.TabIndex = 0; this.treeView1.AfterSelect += new System.Windows.Forms.TreeViewEventHandler(this.treeView1_AfterSelect);
//
// Form1
//
this.AutoScaleBaseSize = new System.Drawing.Size(6, 14); this.ClientSize = new System.Drawing.Size(292, 266); this.Controls.Add(this.treeView1); this.Name = "Form1"; this.Text = "Form1"; this.ResumeLayout(false);
}
#endregion
/// <summary>

[STAThread]
static void Main()
{
Application.Run(new Form1());
}
private void treeView1_AfterSelect(object sender, System.Windows.Forms.TreeViewEventArgs e)
{
string s = treeView1.SelectedNode.Tag.ToString(); string s2 = treeView1.SelectedNode.Text.ToString();
}
}
}
