在MVC 5中使用ModelClientValidationRule引发错误? [英] Error throws using ModelClientValidationRule in MVC 5?

问题描述

我尝试在MVC 5 Project中进行自定义客户端验证.当我添加以下代码时:

I try to do the custom client side validation in MVC 5 Project. When I add the following code:

 public IEnumerable<ModelClientValidationRule> GetClientValidationRules(ModelMetadata metadata, ControllerContext context)
 {
    //Some Validation Here
 }

我收到以下错误:

找不到类型名称'ModelClientValidationRule'.此类型已转发到程序集'System.Web.WebPages，版本= 2.0.0.0，区域性=中性，PublicKeyToken = 31bf3856ad364e35'.考虑添加对该程序集的引用.

The type name 'ModelClientValidationRule' could not be found. This type has been forwarded to assembly 'System.Web.WebPages, Version=2.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35'. Consider adding a reference to that assembly.

但是当我检查web.config文件时，我使用的是从0.0开始支持的WebPages版本

But when I check the web.config file, I am using WebPages version supported from 0.0

<assemblyIdentity name="System.Web.WebPages" publicKeyToken="31bf3856ad364e35"/>
   <bindingRedirect oldVersion="0.0.0.0-3.0.0.0" newVersion="3.0.0.0"/>
</dependentAssembly>

推荐答案

我的System.Web.Mvc被删除，当我重新添加它时，它开始给我您提到的此错误.原因是，早先我使用的是System.Web.Mvc [3.0.0.1]，它被删除，而在添加时，我添加了System.Web.Mvc [4.0.0.1].因此，为解决此问题，我删除了System.Web.Mvc [4.0.0.1]并添加了System.Web.Mvc [3.0.0.1].

My System.Web.Mvc got deleted and when I added it back, it started giving me this error that you have mentioned. The reason for it was that, earlier I was using System.Web.Mvc [3.0.0.1], which got deleted and while adding back, I added System.Web.Mvc [4.0.0.1]. So, to fix this issue, I deleted System.Web.Mvc [4.0.0.1] and added System.Web.Mvc [3.0.0.1].
