【Windows API】获取卷标、卷名

 1、卷->卷标

使用FindFirstVolume()和FindNextVolume()函数体系，枚举系统所有卷（Volume）的例子，然后获取卷标、卷类型。这个方式可以枚举出没有驱动器号（卷标）的卷。

int TestMode1()
{
    HANDLE hVolume = INVALID_HANDLE_VALUE;
    TCHAR tszVolumeName[MAX_PATH] = {0};
    TCHAR tszVolumePath[MAX_PATH] = {0};
    BOOL bRet;

    DWORD dwError;
    DWORD dwCount;
    UINT nDriveType;

    //1、获取卷名称
    hVolume = FindFirstVolume(tszVolumeName, ARRAYSIZE(tszVolumeName));

    if (hVolume == INVALID_HANDLE_VALUE)
    {
        wprintf(_T("FindFirstVolume() failed, error code = %d"), GetLastError());
        return -1;
    }

    while (1)
    {
        //2、获取卷路径
        dwCount = ARRAYSIZE(tszVolumePath);
        bRet = GetVolumePathNamesForVolumeName(tszVolumeName, tszVolumePath, dwCount, &dwCount);

        if (!bRet)
        {
            dwError = GetLastError();
            wprintf(_T("GetVolumePathNamesForVolumeName() failed, error code = %d"), dwError);

            getchar();
            return -1;
        }

        //3、获取驱动器类型
        nDriveType = GetDriveType(tszVolumePath);

        wprintf(_T("Volume name: %s\r\n"), tszVolumeName);
        wprintf(_T("Volume path: %s\r\n"), tszVolumePath);
        wprintf(_T("Drive type: %d\r\n\r\n"), nDriveType);

        bRet = FindNextVolume(hVolume, tszVolumeName, ARRAYSIZE(tszVolumeName));

        if (!bRet)
        {
            dwError = GetLastError();

            if (dwError != ERROR_NO_MORE_FILES)
            {
                wprintf(_T("FindNextVolume() failed, error code = %d"), dwError);
                return -1;
            }

            break;
        }
    }

    wprintf(_T("Test 2 end!\r\n\r\n"));
    //getchar();

    return 0;
}

输入

 

2、卷标->卷名

通过卷标（驱动器号）获取卷名，需要使用GetVolumeNameForVolumeMountPoint()函数。

int TestMode2()
{
    TCHAR tszLogicDriveStrings[1024] = {0};
    LPCTSTR szDrive = NULL;
    TCHAR tszVolumeName[MAX_PATH];

    GetLogicalDriveStrings(sizeof(tszLogicDriveStrings) / sizeof(TCHAR) - 1, tszLogicDriveStrings);
    szDrive = (LPCTSTR)tszLogicDriveStrings;

    do
    {
        GetVolumeNameForVolumeMountPoint(szDrive, tszVolumeName, sizeof(tszVolumeName) / sizeof(TCHAR));
        wprintf(_T("Drive %s, Volume name: %s\r\n"), szDrive, tszVolumeName);
        szDrive += (lstrlen(szDrive) + 1);
    } while (*szDrive != _T('\x00'));

    wprintf(_T("\r\nTest 1 end!\r\n\r\n"));

    return 0;
}

输出
