无法投入'ASP.MyControlName_ascx'类型的对象来键入'MyControlName'

我有一个使用asp.net构建的网站。无法投入'ASP.MyControlName_ascx'类型的对象来键入'MyControlName'

在我的本地电脑这工作正常。但我这个部署在服务器上后，我得到了以下错误味精当我尝试去到一个页面

--Data--System.Collections.ListDictionaryInternal--Base Exception--System.InvalidCastException: Unable to cast object of type 'ASP.uc_eventmanagment_skill_skillbind_ascx' to type 'HRMS.uc.Skill.SkillBind'.

    at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)

加载ASCX文件我用这个代码

  SkillBind SkillBind = (SkillBind)LoadControl("/uc/EventManagment/Skill/SkillBind.ascx"); 
      SkillBind.ID = "SkillBind"; 
      pHolderContainer.Controls.Add(SkillBind);

的哪些错误？

您在使用'Page.LoadControl'加载'skillbind' ASCX控制？显示更多详细信息，包括代码背后的ASCX和ASPX页面标记。 –

@TetsuyaYamamoto嗨朋友更新了这个问题 –

问题似乎添加用户控件到页面之前，源于ID属性的分配：

SkillBind.ID = "SkillBind"; 
pHolderContainer.Controls.Add(SkillBind);

回到与web表单过去的时候，我发现用户控制前应加Control继承容器分配给它的任何属性，通过交换二，三线，使用户控制，即工作：

SkillBind SkillBind = (SkillBind)LoadControl("/uc/EventManagment/Skill/SkillBind.ascx"); 
pHolderContainer.Controls.Add(SkillBind); // assign user control first 
SkillBind.ID = "SkillBind"; // then setting ID attribute

另外，不要忘了包括ASPX页面（或多个）该基准指令行持SkillBind控制：

<%@ Reference Control="/uc/EventManagment/Skill/SkillBind.ascx" %>

然后添加在web.config中的开发版本这个元素来冲洗掉这样的错误（可选）：

<compilation batch="false"/>

之后，尝试清理&重建项目。
