Thanks for the answers.
感谢您的回答。
This worked for me:
这对我有用：
WCHAR fileName[_MAX_PATH];
DWORD size = GetModuleFileName(g_dllHandle, fileName, _MAX_PATH);
fileName[size] = NULL;
DWORD handle = 0;
size = GetFileVersionInfoSize(fileName, &handle);
BYTE* versionInfo = new BYTE[size];
if (!GetFileVersionInfo(fileName, handle, size, versionInfo))
{
delete[] versionInfo;
return;
}
// we have version information
UINT len = 0;
VS_FIXEDFILEINFO* vsfi = NULL;
VerQueryValue(versionInfo, L"\", (void**)&vsfi, &len);
aVersion[0] = HIWORD(vsfi->dwFileVersionMS);
aVersion[1] = LOWORD(vsfi->dwFileVersionMS);
aVersion[2] = HIWORD(vsfi->dwFileVersionLS);
aVersion[3] = LOWORD(vsfi->dwFileVersionLS);
delete[] versionInfo;

If you want programmatic access, see Version Informationin MSDN for the APIs and data structures you need.
如果您想要以编程方式访问，请参阅MSDN 中的版本信息以了解您需要的 API 和数据结构。

Looks like you need to access the VS_VERSION_INFO resource; http://www.microsoft.com/msj/0498/c0498.aspx
看起来你需要访问 VS_VERSION_INFO 资源；http://www.microsoft.com/msj/0498/c0498.aspx

It should be there in the properties (version tab) when you open it in windows explorer
当您在 Windows 资源管理器中打开它时，它应该在属性（版本选项卡）中
