C# 获取指定路径下的文件结构（树形结构）

 namespace Vue.Content
 {
     public class FileNames
     {
         public int id { get; set; }
         public string text { get; set; }
         public state state { get; set; }
         public List<FileNames> children { get; set; }
         public string icon { get; set; }
     }
     public class state
     {
         public bool opened { get; set; }
     }
     //以上字段为树形控件中需要的属性
     public class GetSystemAllPath : Controller
     {
         //获得指定路径下所有文件名
         public static List<FileNames> getFileName(List<FileNames> list, string filepath)
         {
             DirectoryInfo root = new DirectoryInfo(filepath);
             foreach (FileInfo f in root.GetFiles())
             {
                 list.Add(new FileNames
                 {
                     text = f.Name,
                     state = new state { opened = false },
                     icon = "jstree-file"
                 });
             }
             return list;
         }
         //获得指定路径下的所有子目录名
         // <param name="list">文件列表</param>
         // <param name="path">文件夹路径</param>
         public static List<FileNames> GetallDirectory(List<FileNames> list, string path) {
             DirectoryInfo root = new DirectoryInfo(path);
             var dirs = root.GetDirectories();
             if (dirs.Count()!=) {
                 foreach (DirectoryInfo d in dirs)
                 {
                     list.Add(new FileNames
                     {
                         text = d.Name,
                         state = new state { opened = false },
                         children = GetallDirectory(new List<FileNames>(), d.FullName)
                     });
                 }
             }
             list = getFileName(list, path);
             return list;
         }
     }
 }

以上为核心部分！！！

后台返回代码：Sample/GetAllPath

[HttpGet("[action]")]
        public List<FileNames> GetAllPath() {
            //获取当前系统的根路径
            string rootpath = $"{hostingEnv.ContentRootPath}/";
            var list = GetSystemAllPath.GetallDirectory(new List<FileNames>(), rootpath).ToArray();
            return list.ToList();
        }

前台Html：

<div id="demo"></div>

js部分：

  $('#demo')
             //jstree listen for event
             .on('changed.jstree', function (e, data) {
                 if (data && data.selected && data.selected.length) {
                     $('#selectpath').val(data.instance.get_path(data.selected[0], "/", 0));
                 } else {
                     $('#selectpath').val('Select a file from the tree.');
                 }
             }).jstree({
                 'core': {
                     'data': {
                         "url": "api/Sample/GetAllPath",
                         "data": function (node: any) {
                             return { "id": node.id };
                         }
                     }
                 }
         });

前端树形控件使用的是jstree,具体使用方法可以见其官网：https://www.jstree.com/
