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()!=0) {          
                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/
