问题描述

大家好,



无法将Microsoft.Office.Interop.Excel.ApplicationClass类型的COM对象转换为接口类型''Microsoft.Office .Interop.Word._Application'。此操作失败,因为对于具有IID{00020970-0000-0000-C000-000000000046}的接口的COM组件上的QueryInterface调用由于以下错误而失败:不支持此类接口(HRESULT异常:0x80004002



我收到此例外:



((Word._Application)WordApp).Quit();



请给我任何建议来解决它..



谢谢..

问候。


Hi All,

Unable to cast COM object of type ''Microsoft.Office.Interop.Excel.ApplicationClass'' to interface type ''Microsoft.Office.Interop.Word._Application''. This operation failed because the QueryInterface call on the COM component for the interface with IID ''{00020970-0000-0000-C000-000000000046}'' failed due to the following error: No such interface supported (Exception from HRESULT: 0x80004002

I am getting this exception at:

((Word._Application)WordApp).Quit();

please give me any suggestion to resolve it..

Thank you..
