Asp.net mvc 4 在视图中显示目录列表

我尝试在视图中创建目录列表。我的模型是：

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)

                                }

在视图中，我使用了新的UploadViewModel:@model SenecaFormsServer.Areas.Dashboard.Models.UploadViewModel

对于复选框：

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

                                }                              



                            </div>

但我仍然得到了错误：

模板只能用于字段访问、属性访问、一维数组索引或单参数自定义索引器表达式

如果我尝试我的观点：

<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>

@foreach（Model.Directories中的var项）
{
@*@CheckBoxFor（model=>true，item）*@
@CheckBoxFor（m=>m.目录，新的{@checked=“checked”}）；
@LabelFor（model=>model.Directories）
}                                    

我得到这个错误：

无法将类型“string[]”隐式转换为“bool”

Thank you的可能重复项。我更新了我的帖子

[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);
        }

<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>
