如何解决该对象在引用com +元素

我使用C＃MVC WEB API进行编码。当我引用COM +元素时，它会弹出异常和异常。消息为“ JUDEMAP.GOGOMAP1”不包含“ OueryAll”的定义。”。以下控制器代码是bug所在。发生：

   public class APPLE0030Controller : ApiController
    {
        [HttpPost]
        [Route("api/APPLE0030/Index")]
        public object Index()
        {
            appleBase.SQuery dObjOut = new appleBase.SQuery();
            dynamic sysObj;
            try
            {
                sysObj = Activator.CreateInstance(Type.GetTypeFromProgID("JUDEMAP.GOGOMAP1",true));
                dObjOut = sysObj.OueryAll();
                dObjOut.state = "Success";
                dObjOut.msg = "Work";
                return dObjOut;
            }
            catch (Exception ex)
            {
                dObjOut.state = "Fail" ;
                dObjOut.msg = "Not work," + ex.Message;
            }
            return dObjOut;
        }
    }
}

错误在这里：

dObjOut = sysObj.OueryAll();

我已经检出COM +元素：1.COM +元素属性设置正确。 a）检查组件COM-Visible。 b）检查COM互操作的注册。 c）在没有密码的情况下对组件进行签名成功。 d）COM +项目的AssemblyInfo.cs已经在下面添加代码

[assembly: ApplicationName("APPO4600")]       //'*setting COM+ element name 
[assembly: ApplicationActivation(ActivationOption.Server)]
[assembly: ApplicationAccessControl(false)]

COM +项目代码如下：GOGOMAP1.cs
