error LNK2019: unresolved external symbol __imp_SetupDiDestroyDeviceInfoList 错误解决

今天把以前代码中取电池信息的类，加入到com工程中。

结果报了Link错误。错误如下：

error LNK2019: unresolved external symbol __imp_SetupDiDestroyDeviceInfoList referenced in function "private: int __cdecl CNewPwrInfo::_EnumBatteryDevicePath(class std::vector > >,class std::allocator> > > > &)" (?_EnumBatteryDevicePath@CNewPwrInfo@@AEAAHAEAV?$vector@V?$CStringT@_WV?$StrTraitATL@_WV?$ChTraitsCRT@_W@ATL@@@ATL@@@ATL@@V?$allocator@V?$CStringT@_WV?$StrTraitATL@_WV?$ChTraitsCRT@_W@ATL@@@ATL@@@ATL@@@std@@@std@@@Z)

查找后发现是需要导入setupapi.lib

在工程属性 link中加入setupapi.lib就可。
