ASP.NET MVC令人讨厌的错误 - 无法找到类型或命名空间名称

Question

我是新来的ASP.NET MVC，我正在创建一个应用程序，使用自动完成功能和jQuery一起搜索联系人。

当我运行该项目时，它加载正常，当我点击提交按钮来搜索姓氏，我收到一个错误。

Server Error in '/' Application.
The resource cannot be found

Requested URL:/Offender/Search

在尝试这个项目我也跟着一起witht罗斯文MVC样品和项目也给了我的错误，以及。

任何帮助表示赞赏！是感谢

我接收的误差如下：

Answer 1

看起来您并未添加对包含实体模型的程序集的引用。

Answer 2

你是否已经添加了对web.config的引用？如果您有任何意见都强类型，那么你将需要添加一个节在你的web.config的“页”节

<pages> 
    ... 
    <add namespace="KOOLSModel"/> 
    <add namespace="System.Web.Mvc"/> 
    ....
