Question

我的MVC5视图在渲染时抛出错误。我不确定为什么，或者如何跟踪它。

错误是：

无法转换类型为＆System; Guid＆＃39;的对象。输入＆＃39; System.String＆＃39;。

razer是：

<div class="form-group">
    @Html.LabelFor(model => model.LogoUrl, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.LogoUrl, new { htmlAttributes = new { @class = "form-control" } })
        @Html.ValidationMessageFor(model => model.LogoUrl, "", new { @class = "text-danger" })
    </div>
</div>

<div class="form-group">
    @Html.LabelFor(model => model.FullTimeEnrollment, htmlAttributes: new { @class = "control-label col-md-2" })
    <div class="col-md-10">
        @Html.EditorFor(model => model.FullTimeEnrollment, new { htmlAttributes = new { @class = "form-control" } })
        @* This next line errors, not sure why *@
        @Html.ValidationMessageFor(model => model.FullTimeEnrollment, "", new { @class = "text-danger" })  
    </div>
</div>

模型的定义如下：

public class Organization : BaseEntity, IAuditableEntity
{
    //...
    [Display(Name = "FullTime Enrollment")]
    public string FullTimeEnrollment { get; set; }
    //...
}

我的控制器正在加载视图：

public ActionResult organizationdetails(Guid? id)
{
    if (!IsAuthenticated("You must be logged in to access this page.", string.Empty))
    {
        return RedirectToAction("Index", "Submission", new { returnUrl = Request.Url.AbsolutePath });
    }
    ViewData["OrgId"] = id;
    ViewBag.Title = id == Guid.Empty ? "Create Organization" : "Edit Organization";
    var org = db.Organization.Find(id);
    ViewBag.OrganizationTypes = Lookups.GetCached(CachedLists.OrganizationTypes) as List<OrganizationType>;

    return View(org);
}

错误发生在＆＃39; @ Html.ValidationMessageFor（model =＆gt; model.FullTimeEnrollment＆＃39;。当我检查控制器时，模型看起来很好.FullTimeEnrollment为空。

如何调试此类问题？
