显示视图中的目录列表

Question

我尝试在视图中创建目录列表。我的模特是：

public class UploadModel
    {

        [Required]
        [Display(Name = "FormToUpload", ResourceType = typeof(Resources.Entity.Form))]
        public HttpPostedFileBase UploadData { get; set; }
        public string[] Directories { get; set; }


    }

这是控制器：

[HttpGet]
        public ActionResult UploadFile(string designId)
        {
             UploadModel model = new UploadModel();
            string customerSchema = SfsHelpers.StateHelper.GetSchema();
            TemplateLibraryEntry entry = GetTemplateLibraryEntry(designId, customerSchema);
            var path = Path.Combine(Server.MapPath("~/"), entry.FilePath);

            model.Directories = Directory.GetFiles(path, "*", SearchOption.AllDirectories);
            return View(model);
        }

这是我的观点：

<div class="form-group">
                                @foreach (var item in Model.Directories )
                                {
                                    @Html.CheckBoxFor(model => true, item)
                                    @Html.LabelFor(model => model.Directories)

                                }

但是我收到了这个错误：

模板只能用于字段访问，属性访问，单维数组索引或单参数自定义索引器表达式。

谢谢

我现在就这样：

 public class UploadViewModel
    {

        private UploadModel _uploadModel;

        public string[] Directories { get; set; }

        public UploadViewModel(UploadModel uploadModel)
        {
            _uploadModel = uploadModel;


        }
    }



public class UploadModel
    {

        [Required]
        [Display(Name = "FormToUpload", ResourceType = typeof(Resources.Entity.Form))]
        public HttpPostedFileBase UploadData { get; set; }
        public string[] Directories { get; set; }


    }

在视图中我使用新的UploadViewModel：@model SenecaFormsServer.Areas.Dashboard.Models.UploadViewModel

和复选框：

<div class="form-group">
                                @foreach (var item in Model.Directories )
                                {
                                    @Html.CheckBoxFor(model => true, item)
                                    @Html.LabelFor(model => model.Directories)

                                }                              



                            </div>

和我的上传方法：

[HttpGet]
        public ActionResult UploadFile(string designId,UploadModel model)
        {
             UploadModel model = new UploadModel();

            UploadViewModel uploadViewModel = new UploadViewModel(model);
            string customerSchema = SfsHelpers.StateHelper.GetSchema();
            TemplateLibraryEntry entry = GetTemplateLibraryEntry(designId, customerSchema);
            var path = Path.Combine(Server.MapPath("~/"), entry.FilePath);

            //model.Directories = Directory.GetFiles(path, "*", SearchOption.AllDirectories);
            uploadViewModel.Directories = Directory.GetFiles(path, "*", SearchOption.AllDirectories);

            return View(uploadViewModel);
        }

但我仍然收到错误：

模板只能用于字段访问，属性访问，单维数组索引或单参数自定义索引器表达式。

如果我尝试这个观点：

<div class="form-group">
                                @foreach (var item in Model.Directories )
                                {
                                    @*@Html.CheckBoxFor(model => true, item)*@
                                    @Html.CheckBoxFor(m => m.Directories, new { @checked = "checked" });
                                    @Html.LabelFor(model => model.Directories)

                                }                                    


                            </div>

我收到此错误： 无法将类型'string []'隐式转换为'bool'
