80040154未在Outlook 2010加载项中注册类错误 [英] 80040154 Class not registered ERROR in Outlook 2010 Add In

问题描述

我正在使用Visual Studio 2010创建Outlook 2010加载项.我尝试创建一个新的Outlook AppointmentItem，以期最终可以将其添加到日历中.

I am using Visual Studio 2010 to create a Outlook 2010 Add In. I try to create a new Outlook AppointmentItem to work with thinking that I can add it to the calendar eventually.

Microsoft.Office.Interop.Outlook.AppointmentItem tempApp = new Microsoft.Office.Interop.Outlook.AppointmentItem();

但是当AddIn运行并尝试创建AppointmentItem对象时，我在上面的行中收到此错误.

But when the AddIn runs and trys to create the AppointmentItem object, I get this error on the line above.

System.Runtime.InteropServices.COMException was unhandled by user code
      Message=Retrieving the COM class factory for component with CLSID {00061030-0000-0000-C000-000000000046} failed due to the following error: 80040154 Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)).
      Source=mscorlib
      ErrorCode=-2147221164

我该怎么做才能注册课程"?我猜它与Microsoft.Office.Interop.Outlook.dll在某种程度上有关.

What can I do to "register the class"? I'm guessing it has to do with Microsoft.Office.Interop.Outlook.dll in some way.

推荐答案

异常消息不是很有帮助，他们可以使用COM声明做得更好.这是设计使然，该类未注册.您必须使用Application.CreateItem()方法创建它的实例.

The exception message is not very helpful, they could have done a better job with the COM declaration. This is by design, the class is not registered. You must create an instance of it with the Application.CreateItem() method.
