TreeView如何显示目录？下面是我的代码DirectoryInfodirectoryInfo=newDirectoryInfo(@"C:UsersShahulDocumentsVisualStudio2010ProjectsTreeViewTreeViewbinFileExplorer");privatevoidForm1_Load(objectsender,EventArgse){if(Directory.Exists("FileExplorer")){try{[]DirectoryInfo=directoryInfo.GetDirectories();foreach(FileInfofileindirectoryInfo.GetFiles()){if(file.Exists){TreeNodenodes=treeView.Nodes[0].Nodes.Add(file.Name);}}if(directories.Length>0){foreach(DirectoryInfodirectoryindirectories){TreeNodenode=treeView.Nodes[0].Nodes.Add(directory.Name);node.ImageIndex=node.SelectedImageIndex=0;foreach(FileInfofileindirectory.GetFiles()){if(file.Exists){TreeNode节点=treeView.Nodes[0].Nodes[node.Index].Nodes.Add(file.Name);}}}}}catch(Exceptionex){MessageBox.Show(ex.Message);}}}当我运行时，我得到一个空白的树状图？无法弄清楚错误是什么？这是我在StackOverflow上的第一篇文章。这应该可以解决您的问题，不过我尝试了WinForm：publicForm1(){InitializeComponent();DirectoryInfodirectoryInfo=newDirectoryInfo(@"C:UsershikumaDocumentsIR");如果(directoryInfo.Exists){treeView1.AfterSelect+=treeView1_AfterSelect;BuildTree(directoryInfo,treeView1.Nodes);}}privatevoidBuildTree(DirectoryInfodirectoryInfo,TreeNodeCollectionaddInMe){TreeNodecurNode=addInMe.Add(directoryInfo.Name);foreach(FileInfofileindirectoryInfo.GetFiles()){curNode.Nodes.添加（文件全名，文件名）；}foreach（DirectoryInfo.GetDirectories（）中的DirectoryInfo子目录）{BuildTree（subdir，curNode.Nodes）;}}privatevoidtreeView1_AfterSelect(objectsender,TreeViewEventArgse){if(e.Node.Name.EndsWith("txt")){this.richTextBox1.Clear();StreamReaderreader=newStreamReader(e.Node.Name);this.richTextBox1.Text=reader.ReadToEnd();读者。关闭（）；这是一个如何在富文本框中打开文件的简单示例，它可以改进很多:)。如果有帮助，您可能想标记为答案或投票:)！试试这个：（小心确保您的directoryInfo位置包含一些文件夹）DirectoryInfodirectoryInfo=newDirectoryInfo(@"C:UsersShahulDocumentsVisualStudio2010ProjectsTreeViewTreeViewbinFileExplorer");privatevoidForm1_Load(objectsender,EventArgse){if(directoryInfo.Existtry{treeView.Nodes.Add(directoryInfo.Name);DirectoryInfo[]directories=directoryInfo.GetDirectories();foreach(FileInfofileindirectoryInfo.GetFiles()){if(file.Exists){TreeNodenodes=treeView.Nodes[0].Nodes.Add(file.Name);}}if(directories.Length>0){foreach(目录中的DirectoryInfo目录){TreeNodenode=treeView.Nodes[0].Nodes.Add(directory.Name);node.ImageIndex=node.SelectedImageIndex=0;foreach(FileInfofileindirectory.GetFiles()){if(file.Exists){TreeNodenodes=treeView.Nodes[0].Nodes[node.Index].Nodes.Add(file.Name);}}}}}catch(Exceptionex){MessageBox.Show(ex.Message);}}}DirectoryInfo.Exists("文件资源管理器“）将要在调试模式下运行时，检查“C:UsersShahulDocumentsVisualStudio2010ProjectsTreeViewTreeViewbindebugFileExplorer”而不是“C:UsersShahulDocumentsVisualStudio2010ProjectsTreeViewTreeViewbinFileExplorer”试试这个：privatevoidForm1_Load(objectsender,EventArgse){如果(directoryInfo.Exists){try{treeView.Nodes.Add(LoadDirectory(directoryInfo));}catch(Exceptionex){MessageBox.Show(ex.Message);}}}privateTreeNodeLoadDirectory(DirectoryInfodi){if(!di.Exists)返回null;TreeNodeoutput=newTreeNode(di.Name,0,0);foreach(varsubDirindi.GetDirectories()){try{output.Nodes.添加（加载目录（子目录））；}catch(IOExceptionex){//处理错误}catch{}}foreach(varfileindi.GetFiles()){if(file.Exists){output.Nodes.Add(file.Name);}}返回输出；最好将目录解析拆分为递归方法，这样您就可以一直沿着树向下走。这将阻止用户界面，直到它完全加载-但修复它超出了这个答案的范围......？如果所有分享的内容对你有用，需要进一步了解C#学习教程，希望大家多多关注。本文收集自网络，不代表立场。如涉及侵权，请点击右侧联系管理员删除。如需转载请注明出处：
