Question

我真的没有理解为什么每当我的RolesController将逻辑呈现给各自的View时我都会得到Http Error 500。这适用于MVC5应用程序。

请找到以下内容：

RolesController.cs

        [Route("/Roles")]
        public ActionResult Index()
        {
            if (TempData["StatusMessage"] != null)
            {
                ViewBag.StatusMessage = TempData["StatusMessage"].ToString();
            }
            else
            {
                ViewBag.StatusMessage = "";
            }

            var roles = db.Roles.ToList();
            return View("Index", roles);
        }

        // GET: /Roles/Create
        public ActionResult Create()
        {
          return View();
        }



        [HttpPost]
        [ValidateAntiForgeryToken]
        public async Task<ActionResult> Create([Bind(Include = "Name,Description")] ApplicationRole model)
        {
            try
            {
                if (ModelState.IsValid)
                {
                    var role = new ApplicationRole()
                    {
                        Name = model.Name,
                        Description = model.Description
                    };

                    var roleManager = new RoleManager<ApplicationRole>(new RoleStore<ApplicationRole>(db));
                    var result = await roleManager.CreateAsync(role);
                    if (result.Succeeded)
                    {
                        return RedirectToAction("Index", "Roles");
                    }
                    else
                    {
                        AddErrors(result);
                    }
                }
            }
            catch (Exception e)
            {
                Console.WriteLine(e.ToString());
            }
            // If we got this far, something failed, redisplay form
            return View(model);
        }

查看：

@model User_Manager_Interface.Models.ApplicationRole
@{
    Layout = "~/Views/Shared/_Layout.cshtml";
}


<div class="contenttitle">
    <h2 class="form"><span>Create A New Role</span></h2>
</div>

@using (Html.BeginForm("Create", "Roles", FormMethod.Post, new { @class = "stdform", role = "form" }))
{
    @Html.AntiForgeryToken()

    @Html.ValidationSummary()

    <p>
        <label>@Html.LabelFor(model => model.Name)</label>
        <span class="field">
            <input type="text" name="name" id="name" class="smallinput" />
        </span>
        @Html.ValidationMessageFor(model => model.Name)
        <small class="desc">Name of the role.</small>
    </p>

    <p>
        <label>@Html.LabelFor(model => model.Description)</label>
        <span class="field">
            <input type="text" name="description" id="description" class="longinput" />
        </span>
        @Html.ValidationMessageFor(model => model.Description)
        <small class="desc">A short description for the role.</small>
    </p>

    <br clear="all" /><br />

    <p class="stdformbutton">
        <button class="submit radius2">Create</button>
        <input type="reset" class="reset radius2" value="Reset Form" />
    </p>
}

@section Scripts {
    @Scripts.Render("~/bundles/forms")
}

型号：

 public class ApplicationRole : IdentityRole
    {
        [Display(Name = "Description")]
        [StringLength(100, MinimumLength = 5)]
        public string Description { get; set; }
    }

是编译器不知道在运行时呈现什么视图的问题？我能做错什么？

Answer 1

好。几乎放弃后，我偶然发现了这个SO帖子：

asp.net mvc 3 handleerror global filter always shows IIS status 500 page

看了@DarinDimitrov的解决方案。

所以我做了以下事情：

我在 web.config

<customErrors mode="On" />

我将此功能添加到 ErrorController.cs：

public ActionResult Index() { throw new Exception("error"); }
确保我的 Error.cshtml 文件的内容大小超过1KB才能呈现视图。

这解决了这个问题。结果，这也解决了我的这个待定的SO帖子，可以在这里找到：Object Moved Here - RedirectToAction

GET http：// localhost / Roles / Create 500（内部服务器错误）
