XVAL和ASP.Net MVC 2 AddModelStateErrors问题

问题描述

限时删除！！

我有我一直在使用XVAL成功了相当一段时间的应用程序。这是最近更新到MVC 2。

I have an application that I've been using xVal successfully on for quite some time. It was recently updated to MVC 2.

我用的是标准的DataAnnotations属性在我的域模型，这也实现调用的一个DataAnnotationsValidationRunner验证（）方法。如果有任何错误，该方法将引发RulesException。

I use the standard DataAnnotations attributes on my domain models, which also implement a "Validate()" method that calls the DataAnnotationsValidationRunner. If there are any errors, that method throws a RulesException.

在我的控制器，我使用RulesException非常典型的抓

In my controllers, I use the very typical catch for RulesException

catch (RulesException e)
{
    e.AddModelStateErrors(ModelState, "err");
}

所有典型的东西，几乎直接从实例，并且做工精细直到最近（我怀疑开始在我的MVC1时间的问题 - > MVC2更新

All typical stuff, nearly straight from the examples, and working fine until recently (I suspect the problems started at the time of my MVC1 -> MVC2 update.

所以，问题是这样的：当AddModelStateErrors方法被调用，我得到一个System.EntryPointNotFoundException：入口点未找到，它是从未来了System.Collections.Generic.ICollection 1.get_Count（）在System.Web.Mvc.Html.ValidationExtensions.ValidationMessageHelper（的HtmlHelper的HtmlHelper，modelMetadata modelMetadata，字符串前pression，字符串validationMessage，IDictionary的 2 htmlAttributes）在System.Web程序。 Mvc.Html.ValidationExtensions.ValidationMessage（的HtmlHelper的HtmlHelper，MODELNAME字符串，字符串validationMessage，IDictionary`2 htmlAttributes）在ASP.views_user_edit_aspx .__ RenderContent2 ... {剪断，因为它是标准的从那里}

So the problem is this: When the AddModelStateErrors method gets called, I'm getting a "System.EntryPointNotFoundException : Entry point was not found", which is coming from System.Collections.Generic.ICollection1.get_Count() at System.Web.Mvc.Html.ValidationExtensions.ValidationMessageHelper(HtmlHelper htmlHelper, ModelMetadata modelMetadata, String expression, String validationMessage, IDictionary2 htmlAttributes) at System.Web.Mvc.Html.ValidationExtensions.ValidationMessage(HtmlHelper htmlHelper, String modelName, String validationMessage, IDictionary`2 htmlAttributes) at ASP.views_user_edit_aspx.__RenderContent2...{snipped, as it's standard from there}

我已经看了两个code为XVAL的方法和扩展的HtmlHelper，我似乎无法弄清楚发生了什么事情。

I've looked at both the code for xVal's method and the HtmlHelper Extension, and I can't seem to figure out what's going on.

任何想法？

推荐答案

有同样的问题，但只是解决它：添加以下的web.config或app.config中，移动到MVC2：

Has the same problem but just solved it: add the following to web.config or app.config, for moving to MVC2:

<runtime>
    <assemblyBinding
xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0" newVersion="2.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>

或MVC3：

<runtime>
    <assemblyBinding
xmlns="urn:schemas-microsoft-com:asm.v1">
      <dependentAssembly>
        <assemblyIdentity name="System.Web.Mvc" publicKeyToken="31bf3856ad364e35"/>
        <bindingRedirect oldVersion="1.0.0.0-2.0.0.0" newVersion="3.0.0.0"/>
      </dependentAssembly>
    </assemblyBinding>
  </runtime>
