hidden-field - 为什么我收到 System.Data.Linq.Binary 的 Html.Hidden 错误？

Question

我想将隐藏的 openid 数据发布到一个动作中，在 Razor 中我使用以下代码：

@Html.Hidden("OpenID", Request.QueryString["openid"]);

然后我收到此错误：

Compiler Error Message: CS0012: The type 'System.Data.Linq.Binary' is defined in an     assembly that is not referenced. You must add a reference to assembly 'System.Data.Linq,     Version=3.5.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.

Source Error:

Line 12: <form method="post" action="Register">
Line 13:     @Html.Hidden("OpenID", Request["openid"]);
