C# 使用 FTP 服务器目录填充 TreeView

Question

我在网上搜索过，对此仍然很陌生。请对我有一些耐心。

我想做的是： - 我有一个名为“treeTO”的 TreeView。- 我连接到我的 FTP 服务器，并且想要在树视图中填充此处的所有内容（目录、子目录和文件，无论是什么）。- 这是我到目前为止的代码：

FtpWebRequest request = (FtpWebRequest)WebRequest.Create("ftp://" + ActiveServer.Server + "/");
request.Method = WebRequestMethods.Ftp.ListDirectoryDetails;
request.Credentials = new NetworkCredential(ActiveServer.UserName, ActiveServer.Password);
FtpWebResponse response = (FtpWebResponse)request.GetResponse();
Stream responseStream = response.GetResponseStream();
StreamReader reader = new StreamReader(responseStream);

-这将返回以下文本：日志、数据和 WwwRoot。

我很难将其添加到树视图中，然后循环遍历文件夹以将所有内容添加到树视图中。

当然，您必须将“root”的值替换为 FTP 服务器的 rootURL，并在方法 GetWebRequest() 中将“用户名”和“密码”替换为您的凭据！

您需要这个类来保存详细信息

\n\n

public class FTPListDetail\n{\n        public bool IsDirectory\n        {\n            get\n            {\n                return !string.IsNullOrWhiteSpace(Dir) && Dir.ToLower().Equals("d");\n            }\n        }\n        internal string Dir { get; set; }\n        public string Permission { get; set; }\n        public string Filecode { get; set; }\n        public string Owner { get; set; }\n        public string Group { get; set; }\n        public string Name { get; set; }\n        public string FullPath { get; set; }\n}\n

这是您的 WinForm 应用程序的代码隐藏
