本文讲述C#获取Windows系统目录，如何目录遍历以及将信息捆绑在TreeView中显示出来的实现方法，具体实现代码如下：

using System; using System.Drawing; using System.Collections; using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.IO; namespace 获取系统目录 { public class Form1 : System.Windows.Forms.Form { private System.Windows.Forms.TreeView treeView1;

private System.Windows.Forms.Label label1; public Form1() { InitializeComponent(); FillTree(treeView1, true); // 显示所有文件夹以及文件 } 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 private void InitializeComponent() { this.textBox1 = new System.Windows.Forms.TextBox(); this.label2 = new System.Windows.Forms.Label(); this.label1 = new System.Windows.Forms.Label();
