代码片段

实现目标：可以新建文件夹。默认文件夹排在列表前面并按照时间进行排序。为了减少查询的次数，需要添加一个字段标示是否是文件夹，可置为0，文件置为1，按照这个字段排序，并按照时间进行排序。

为MyFile类添加属性，IsFolder

public int IsFolder { get; set; }

修改文件上传，文件类型为1，并修改文件列表，按照文件类型，时间排序。

        [HttpGet]
        public ActionResult FileList()
        {
            UserInfo userInfo = Session["user"] as UserInfo;
            if (userInfo == null)
            {
                return RedirectToAction("Login", "UserInfo");
            }
            var fileList = _myFileServiceRepository.FindAll(x => x.User.Id == userInfo.Id && !x.IsDelete).OrderBy(x => x.IsFolder).OrderByDescending(x => x.CreateDt);
            ViewBag.UserInfo = userInfo;
            ViewBag.ChildTitle = "我的网盘";
            return View(fileList);
        }

新建文件夹

        public JsonResult CreateFolder()
        {
            UserInfo userInfo = Session["user"] as UserInfo;

            if (userInfo == null)
            {
                RedirectToAction("Login", "UserInfo");
            }
            string folderPath = Request.Params["folderPath"];
            string folderName = Request.Params["folderName"];
            if (string.IsNullOrEmpty(folderName))
            {
                throw new ArgumentNullException("文件夹名称不能为空");
            }
            //检查文件夹是否已经存在
            var count = _myFileServiceRepository.FindAll(x => x.User.Id == userInfo.Id && x.IsFolder == 0 && x.IsDelete == false && x.FileName.Contains(folderName)).Count();
            userInfo = _userInfoServiceRepository.Find(x => x.Id == userInfo.Id);
            if (count > 0)
            {
                //如果不存在，则新建，否则进行自动重命名
                folderName = folderName + "(" + (count + 1).ToString() + ")";
            }
            if (string.IsNullOrEmpty(folderPath))
            {
                folderPath = "/NetDisk/" + userInfo.UserName;
            }
            MyFile folder = new MyFile()
            {
                FilePath = folderPath + '/' + folderName,
                FileName = folderName,
                CreateDt = DateTime.Now,
                User = userInfo,
                FileExt = string.Empty,
                FileIcon = "/Content/Images/FolderType.png",
                FileMd5 = string.Empty,
                FileSize = 0,
                IsDelete = false,
                ModifyDt = DateTime.Now
            };
            try
            {
                _myFileServiceRepository.Add(folder);
                _myFileServiceRepository.SaveChanges();
            }
            catch (Exception)
            {
                return new JsonResult() { Data = new JavaScriptSerializer().Serialize(new { code = 500, msg = "创建失败" }) };
            }
            return new JsonResult() { Data = new JavaScriptSerializer().Serialize(new { code = 200, folder = folder }) };
        }
