一个简单的c#资源管理器.doc

在窗体中加入一个TreeView、RichTextBox、TextBox，布局随便调整吧，双击TreeView加入AfterSelect事件。用如下代码相应替代，一个简单的资源管理器就有了。 using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.IO; namespace MyExplore / / Description of Form1. / public partial class Form1 : Form TreeNode rootnode = new TreeNode(); string str = ; public Form1() InitializeComponent(); rootnode.Text = ; /获得整个系统磁盘驱动 DriveInfo drivers = DriveInfo.GetDrives(); /将盘符名加载到TreeView的顶级节点 foreach (DriveInfo driver in drivers) TreeNode treenode = new TreeNode(); treenode.Text = driver.Name; rootnode.Nodes.Add( treenode); rootnode.Text = System; this.treeView1.Nodes.Add(rootnode); void TreeView1AfterSelect(object sender, TreeViewEventArgs e) if( e.Node.Text != System) str = e.Node.FullPath.Replace(System,string.Empty).Replace(,); this.textBox1.Text = str; DirectoryInfo directoryInfo = new DirectoryInfo(str); try foreach (DirectoryInfo childDirectoryInfo in directoryInfo.GetDirectories() TreeNode directoryNode = new TreeNode(childDirectoryInfo.Name.ToString(); directoryNode.Tag = childDirectoryInfo.Name.ToString(); e.Node.Nodes.Add(directoryNode); this.treeView1.Refresh(); catch ( System.IO.DirectoryNotFoundException ee ) this.textBox1.Text = ee.ToString(); try StringBuilder sb = new StringBuilder(); DirectoryInfo directoryInfo1 = new DirectoryInfo(str); foreach (FileInfo fileInfo in directoryInfo1.GetFiles(*.*) sb.AppendLine(fileInfo.Name); this.richTextBox1.Text = sb.ToString();
