【CSharp】加载指定目录下的所有子目录和文件名称到TreeView中

作者:xqf222 / 发布于2014/2/25/ 677

使用线程加载指定目录下的所有子目录和文件名称到TreeView中

界面设计步骤：

从工具箱中拖放一个TreeView(teeView1)和一个Button(button1)到WinForm窗体中

添加引用：

using System.Threading;
using System.IO;

详细代码：


 #region 目录树委托定义
 private delegate void UpdateTreeViewDelegate(TreeNode node);//声明委托类型
 private static string CurrentFolderPath;
 #endregion

 #region 目录树节点操作函数
 /// <summary>
 /// 加载节点到TreeView中
 /// </summary>
 /// <param name="node">TreeNode</param>
 private void AddToTreeView(TreeNode node)
 {
 treeView1.Nodes.Add(node);
 treeView1.Refresh();
 }
 /// <summary>
 /// 递归加载指定目录下的所有子目录和文件树
 /// </summary>
 /// <param name="reg">指定目录路径</param>
 /// <param name="nodes">起始树，将在它下面建立所有子结点</param>
 internal void LoadFolderFileList(string path, TreeNode nodes)
 {
 string[] dirs = Directory.GetDirectories(path);
 string[] files = Directory.GetFiles(path);
 for (int i = 0; i < dirs.Length; i++)
 {
 string[] info = new string[4];
 DirectoryInfo di = new DirectoryInfo(dirs[i]);
 TreeNode node = new TreeNode(di.Name);
 node.Tag = di.FullName;
 try
 {
 if (di.GetDirectories().Length > 0 || di.GetFiles().Length > 0)
 {
 LoadFolderFileList(di.FullName, node);
 }
 else
 {
 continue;
 }
 }
 catch
 {
 continue;
 }
 nodes.Nodes.Add(node);
 }
 for (int i = 0; i < files.Length; i++)
 {

 FileInfo fi = new FileInfo(files[i]);
 TreeNode node = new TreeNode(fi.Name);
 node.Tag=fi.FullName;
 nodes.Nodes.Add(node);

 }
 }

 #endregion





 #region 按钮事件
 private void button1_Click(object sender, EventArgs e)
 {
 FolderBrowserDialog myFolderBrowserDialog = new FolderBrowserDialog();
 myFolderBrowserDialog.ShowDialog();
 if (myFolderBrowserDialog.SelectedPath != "")
 {
 CurrentFolderPath = myFolderBrowserDialog.SelectedPath;
 Thread thread = new Thread(new ThreadStart(LoadFolderMethod));
 thread.Start();
 }
 }
 #endregion

 #region 线程方法
 /// <summary>
 /// 获取指定目录下的所有子目录和文件
 /// </summary>
 private void LoadFolderMethod()
 {
 UpdateTreeViewDelegate loadTreeView = new UpdateTreeViewDelegate(AddToTreeView);
 string[] myPath=CurrentFolderPath.Split('\\');
 TreeNode node=new TreeNode();
 string path;
 foreach (string s in myPath)
 {
 path=s+"\\";
 node = new TreeNode(s);
 node.Tag = path;
 }
 LoadFolderFileList(CurrentFolderPath, node);
 if (treeView1.InvokeRequired)//将读取的根加载至TreeView
 treeView1.BeginInvoke(loadTreeView, node);
 else
 {
 treeView1.Nodes.Add(node);
 }
 }
 #endregion

试试其它关键字

　TreeView　

同语言下

可能有用的
