Asp.net mvc 为什么我的ASP.NET MVC 2应用程序中的EditorFor引发异常？

在我的一个观点中，我对EditorFor有一个奇怪的问题。以下代码引发ArgumentNullException

<%: Html.EditorFor(x => x.Name) %>

---

要传递的属性的编辑器模板是什么样子的？（我假设x.Name是一个字符串，所以在Views/Shared/EditorTemplates中应该有一个名为string.ascx的模板）

为字符串加载的编辑器模板可能不喜欢传递空字符串

---

如果您没有用于字符串的自定义编辑器模板（并且您只需要一个基本文本框），那么就没有理由使用EditorFor。

Yes，“Name”是一个字符串变量。不，我没有自定义编辑器。我想我将跳过EditorFor，但我对为什么它在某些场景中会中断很感兴趣（DisplayFor似乎也会这样）。也许它会和MVC 3一样…是的，这可能是一个热错误，它处理默认的EditorFor字符串模板。我打赌它只是在没有自定义模板的情况下在内部调用Html.TextBox。

<%: Html.TextBoxFor(x => x.Name) %>
