Here is a brief overview of the file browser's general implementation process. For the specific use of these controls, see the online help of C#. You need to use several controls: TreeView (directory tree for display (ListView); used to display the list of files and directories; (Splitter) for TreeView and allows the user to adjust the size of the ListView); other such as: MainMenu, ToolBar, StatusBar, ImageList etc. depending on your actual need. First, create a new C# project (Windows application), named MyFileView, and name the window mainForm, and adjust the main window size (Size). Add controls such as MainMenu, ToolBar, StatusBar, ImageList, etc.. Then, add the TreeView control, which is named treeView, and the Dock property is set to Left, and then add the Splitter control, and also set the Dock property to Left. Finally, add the ListView control, named listView, and the Dock property to Fill. As shown in the following figure. The interface is ready, so how can I display folders and files in this interface? This requires us to add code to implement. First, refer to the following namespace: using System; using System.Drawing; using System.Collections; Using System.ComponentModel; using System.Windows.Forms; using System.Data; using System.IO; using System.InteropServices.Runtime; Add the following code in the mainForm_Load event, used to display the directory tree in the treeView control: private void mainForm_Load (object sender, System.EventArgs E) string[] LogicDrives=System.IO.Directory / / get the logical drive (.GetLogicalDrives); TreeNode[] cRoot =new TreeNode[LogicDrives.Length]; for (int i=0; i< LogicDrives.Length; i++) {TreeNode drivesNode=new TreeNode (LogicDrives[i]).Add (treeView.Nodes; (drivesNode); if = "A:\" LogicDrives[i]! LogicDrives[i]! = "B:\") getSubNode (drivesNode, true);}} wherein getSubNode is a method used to obtain sub directory, to create a directory tree node parameter: PathName to create a child node, this node gets the subdirectory parameters under isEnd: marks the end of the end, true. Private, void, getSubNode (TreeNode, PathName, bool, isEnd) { If (isEnd return //exit this!); TreeNode curNode; DirectoryInfo[] subDir; DirectoryInfo curDir=new DirectoryInfo (PathName.FullPath); try (catch{}) {subDir=curDir.GetDirectories}; foreach (DirectoryInfo D in subDir) {curNode= new TreeNode (d.Name); PathName.Nodes.Add (curNode); getSubNode (curNode, false);}} when the mouse click directory on the left side of the node + number, node will start, at this time, should add the following code in the AfterExpand event, in order to obtain this directory and subdirectories nodes: private void treeView_AfterExpand (object sender, System.Windows.Forms.TreeViewEventArgs, e) {try { Foreach (TreeNode, TN, e.Node,.Nodes, in) {if (... Tn.IsExpanded) getSubNode (tn, True)} catch{}} when the mouse click selects the directory node, the right listView control should display the files and directories in this directory. The code is as follows: private, void, treeView_AfterSelect (object Sender, System.Windows.Forms.TreeViewEventArgs E) {listView.Items.Clear (DirectoryInfo); selDir=new DirectoryInfo (e.Node.FullPath); DirectoryInfo[] listDir; FileInfo[] listFile; try listDir=selDir.GetDirectories; listFile=) {(selDir.GetFiles)} (catch{}; foreach (DirectoryInfo D in listDir) ListView.Items.Add (d.Name, 6); foreach (FileInfo D in listFile listView.Items.Add (d.Name));} so far, a simple file browser is made, of course, it is still the primary, and also can't even use it to open a file, it can not display the file and directory icon. No error handling, no safety control...... What it gives you is just a train of thought. 1.
