ASP.NET MVC 5.1 EditorFor和Display不使用自定义模板

突然我的MVC应用程序停止使用我自己的自定义EditorFor或DisplayFor模板。 因为我一直在改变UI，所以我不确定它到底是什么时候失败了。 我将模板放在Shared文件夹下的DisplayTemplates和EditorTemplates 。 我用这个覆盖Global.asax的ViewEnginesCollection ：

 ViewEngines.Engines.Clear(); ViewEngines.Engines.Add(new CSHtmlRazorViewEngine { PartialViewLocationFormats = new string[] { "~/Views/Shared/EditorTemplates/{0}.cshtml", "~/Views/Shared/Partials/{0}.cshtml" } }); 

CSHtmlRazorViewEngine是：

 public sealed class CSHtmlRazorViewEngine : RazorViewEngine { public CSHtmlRazorViewEngine() : base() { this.AreaViewLocationFormats = new string[2] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.cshtml" }; this.AreaMasterLocationFormats = new string[2] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.cshtml" }; this.AreaPartialViewLocationFormats = new string[2] { "~/Areas/{2}/Views/{1}/{0}.cshtml", "~/Areas/{2}/Views/Shared/{0}.cshtml" }; this.ViewLocationFormats = new string[3] { "~/Views/{0}.cshtml", "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; this.MasterLocationFormats = new string[2] { "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; this.PartialViewLocationFormats = new string[2] { "~/Views/{1}/{0}.cshtml", "~/Views/Shared/{0}.cshtml" }; this.FileExtensions = new string[1] { "cshtml" }; } } 

我有点难以理解我突然出错的地方。 关于在哪里检查什么的任何建议？

更新 – 代码示例

这是Office对象的Edit.cshtml页面：

 
 @using (Html.BeginForm("Edit", "Offices", new { id = Model.Office.Id }, FormMethod.Post)) { 
  
 @Html.EditorFor(m => m.Office, new { Regions = Model.Regions, States = Model.States }) } @Html.Partial("Equipments", Model.Equipments)  

这里是要求的Office的EditorFor模板：

 @model Office 
 @Html.Label("Name", "Name:") @Html.TextBox("Name", Model.Name, new { required = string.Empty }) 
 
 @Html.Label("RegionId", "Region:") @Html.DropDownList("RegionId", new SelectList((IEnumerable)ViewData["Regions"], "Id", "Name", Model.RegionId), string.Empty, new { required = string.Empty }) 
 @Html.EditorFor(m => m.Address) 

这是OfficesController.Edit() ActionResult ：

 [HttpGet] public async Task Edit( short id) { if (id > 0) { Office office = await base.Repository.FindSingleOrDefaultAsync(id); if (office != null) { Task<IQueryable> equipments = Task.Run(() => base.Repository.FindEquipment(id)); Task<IQueryable> regions = Task.Run(() => base.Repository.Find()); Task<IQueryable> states = Task.Run(() => base.Repository.Find()); await Task.WhenAll(equipments, regions, states); return base.View(new OfficesView { Equipments = equipments.Result.ToList(), Office = office, Regions = regions.Result, States = states.Result, ViewData = new OfficeViewData { Map = new Map { Center = office.Address.Position.ToPoint(), Polygons = (office.Boundaries != null) ? new Polygon[] { office.Boundaries.ToPolygon() } : null } } }); } } return base.RedirectToAction("List"); } 

没有生成编译或运行时exception。 EditorFor只是默默地找不到模板并生成默认模板。 代码模式几乎为每个其他对象重复。

在查找编辑器模板时，MVC会将EditorTemplates/ segment添加到部分视图名称中。 你可以在这里查看源代码 ，ExecuteTemplate函数。

您已将部分视图位置设置为：

 "~/Views/Shared/EditorTemplates/{0}.cshtml" "~/Views/Shared/Partials/{0}.cshtml" 

在查找Address编辑器模板时，MVC将使用EditorTemplates/Address作为部分视图名称。 这意味着它将检查以下2个部分视图位置：

 ~/Views/Shared/EditorTemplates/EditorTemplates/Address.cshtml ~/Views/Shared/Partials/EditorTemplates/Address.cshtml 

如果它在那里找不到它，它将返回默认的编辑器模板。

您的编辑器模板当前可能位于第一个EditorTemplates文件夹中吗？
