Question

我有一些vb-net-late-binding-operations-无法转换为表达式树错误 VB.Net Late binding operations cannot be converted to an expression tree

我从

更改了网页代码

<%@ Page Language="vb" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Store.WebUI.Entities.ShippingDetails>" %>

到

<%@ Page Language="vb" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage(Of Store.WebUI.Entities.ShippingDetails)" %>

修复了关于后期绑定操作的错误 - 无法转换为表达式树但现在我得到了这个错误。 - 未定义类型“Store.WebUI.Entities.ShippingDetails”。 12 5 - 'Context'不是'ASP.views_cart_checkout_aspx'的成员。 12 5 - 'BeginForm'不是'Html'的成员。 12 15

我的代码是

<%@ Page Language="vb" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage(Of Store.WebUI.Entities.ShippingDetails)" %>

检查Store.WebUI.Entities.ShippingDetails类是否存在，您的解决方案中存在对System.Web.Mvc.dll的引用。如果这没有帮助，请在此处发布课程Store.WebUI.Entities.ShippingDetails。

类型'Store.WebUI.Entities.ShippingDetails'未定义＆amp; 'BeginForm'不是'Html'的成员
