哦！全反射"风格调用！没看到很长时间！

是否可以在\ Microsoft Visual Studio 8 \ VC \ bin \ dumpbin.exe/EXPORTS< file-name> .dll中看到此"setLabel"功能?? 调用.InvokeMember()尚不清楚，我在两侧都看到'clt'变量(甚至作为函数参数...)

如果您已经在进行反射-也许您可以_list_具有"public"签名的所有功能，并确保"setLabel"功能存在?因此，这不是错误的DLL还是强制转换的对象?

Oho ! Full 'reflection' style invoke ! Didn't see that a long time !

Does this 'setLabel' function can be seen in \Microsoft Visual Studio 8\VC\bin\dumpbin.exe /EXPORTS <file-name>.dll ??  It's not clear on what you calling .InvokeMember() - I see 'clt' variable on both sides (even as function parameter...)

And if you already doing reflection - may be you just can _list_ all the function with 'public' signature and make sure that 'setLabel' function exist ? So it's not a wrong DLL or casted object ?
