您忘记了MessageBox类的命名空间:

 using namespace System::Windows;
也许可以试试这个: 系统::Windows::窗体::MessageBox 这是: 系统::Windows::窗体::MessageBox按钮 (你忘了带s)

什么是“MessageBoxButton”?对不起。应该是MessageBoxButtons。它使代码中的错误消失了。在哪里添加此语句?“Eample_1.cpp”或“Form1.h”?看起来这两个文件都不可行。Thank.1>TRACKER:错误TRK0002:未能执行命令:“C:\Program Files(x86)\Microsoft Visual Studio 10.0\VC\bin\CL.exe”@C:\Users\User\AppData\Local\Temp\TMPAB12CE06007FA4AFABB059350E07538E.rsp”。存储控制块地址无效。如何解决这个问题?这似乎是一个无关的问题,提出另一个问题并发布它
