System.Web.Mvc.HtmlHelper
定義」複選框does not contain a definition for
and no extension method
‘複選框’accepting a first argument of type
「System.Web.Mvc.HtmlHelper'`可以找到(是否缺少using指令?或程序集引用)System.Web.Mvc.HtmlHelper「不包含複選框
我改變的web.config這樣的:
<configuration>
<appSettings>
</appSettings>
<connectionStrings>
</connectionStrings>
<pages>
<namespaces>
<add namespace="secondMvc.MyControls"/>
</namespaces>
</pages>
<system.web>
<compilation>
<assemblies>
<add assembly="secondMvc.MyControls" />
</assemblies>
</compilation>
</system.web>
</configuration>
但我有相同的錯誤。 有什麼想法?
你是什麼意思確保你已經添加了第二個MVC.MyControls命名空間?我已經將System.Web.Mvc.Html添加到了我的主Web配置並查看了web.config並仍然出現此錯誤? – Pomster
