正如Michael Walz所说，你需要链接依赖库和dll来修复链接器错误。

为了在Visual Studio中执行此操作

在项目上右键单击 - ＆gt;选择属性 - ＆gt;点击并展开配置属性 - ＆gt;选择链接器 - ＆gt;在链接器下选择输入 在右侧编辑附加依赖项字段以添加libs / dll所在的路径。

也许为时已晚，但我遇到了类似的问题，这是通过在stdafx.h中执行此操作来解决的。

template class __declspec(dllimport) CStringT<char, class StrTraitMFC_DLL<char, class ATL::ChTraitsCRT<char> > >;

在你的情况下，我在猜测

template class __declspec(dllimport) CStringT<wchar_t,class StrTraitMFC_DLL<wchar_t,class ATL::ChTraitsCRT<wchar_t> > >

也许其他人可能会根据您的错误日志...

干杯
