如何以编程方式获取 DLL 或 EXE 文件的版本?
我需要使用 C 或 C++ 中的 Win32 本机 API 获取 DLL 或 EXE 文件的产品版本和文件版本.我要不是寻找 Windows 版本,而是通过右键单击 DLL 文件,选择属性",然后查看详细信息"选项卡所看到的版本号.这通常是一个由四部分组成的虚线版本号 x.x.x.x.
I need to get the product version and file version for a DLL or EXE file using Win32 native APIs in C or C++. I'm not looking for the Windows version, but the version numbers that you see by right-clicking on a DLL file, selecting "Properties", then looking at the "Details" tab. This is usually a four-part dotted version number x.x.x.x.
推荐答案
您将使用 GetFileVersionInfo API.
请参阅 MSDN 上的使用版本信息网站.
See Using Version Information on the MSDN site.
示例:
DWORD verHandle = 0;
UINT size = 0;
LPBYTE lpBuffer = NULL;
DWORD verSize = GetFileVersionInfoSize( szVersionFile, &verHandle);
if (verSize != NULL)
{
LPSTR verData = new char[verSize];
if (GetFileVersionInfo( szVersionFile, verHandle, verSize, verData))
{
if (VerQueryValue(verData,"\",(VOID FAR* FAR*)&lpBuffer,&size))
{
if (size)
{
VS_FIXEDFILEINFO *verInfo = (VS_FIXEDFILEINFO *)lpBuffer;
if (verInfo->dwSignature == 0xfeef04bd)
{
// Doesn't matter if you are on 32 bit or 64 bit,
// DWORD is always 32 bits, so first two revision numbers
// come from dwFileVersionMS, last two come from dwFileVersionLS
TRACE( "File Version: %d.%d.%d.%d
",
( verInfo->dwFileVersionMS >> 16 ) & 0xffff,
( verInfo->dwFileVersionMS >> 0 ) & 0xffff,
( verInfo->dwFileVersionLS >> 16 ) & 0xffff,
( verInfo->dwFileVersionLS >> 0 ) & 0xffff
);
}
}
}
}
delete[] verData;
}
