你爲什麼不我得到的卷名的U盤

Question

如何爲盤符

例如獲得卷名：我怎樣才能卷名G：/

感謝您的幫助

Answer 1

BOOL WINAPI GetVolumeInformation(
    __in_opt LPCTSTR lpRootPathName, 
    __out  LPTSTR lpVolumeNameBuffer, 
    __in  DWORD nVolumeNameSize, 
    __out_opt LPDWORD lpVolumeSerialNumber, 
    __out_opt LPDWORD lpMaximumComponentLength, 
    __out_opt LPDWORD lpFileSystemFlags, 
    __out  LPTSTR lpFileSystemNameBuffer, 
    __in  DWORD nFileSystemNameSize 
);

傳遞體積根路徑（如「C：\」）中，獲得了大量的信息（包括卷名，也稱爲卷標）出來。

可用自Windows 2000

您可以從該代碼得到它：

BOOL WINAPI GetVolumeNameForVolumeMountPoint(
    __in LPCTSTR lpszVolumeMountPoint, 
    __out LPTSTR lpszVolumeName, 
    __in DWORD cchBufferLength 
);

使用下面的代碼片段：

TCHAR volumeName[MAX_PATH + 1] = { 0 }; 
TCHAR fileSystemName[MAX_PATH + 1] = { 0 }; 
DWORD serialNumber = 0; 
DWORD maxComponentLen = 0; 
DWORD fileSystemFlags = 0; 

if (GetVolumeInformation(
    _T("C:\\"), 
    volumeName, 
    ARRAYSIZE(volumeName), 
    &serialNumber, 
    &maxComponentLen, 
    &fileSystemFlags, 
    fileSystemName, 
    ARRAYSIZE(fileSystemName))) 
{ 
_tprintf(_T("Volume Name: %s\n"), volumeName); 
_tprintf(_T("Serial Number: %lu\n"), serialNumber); 
_tprintf(_T("File System Name: %s\n"), fileSystemName); 
_tprintf(_T("Max Component Length: %lu\n"), maxComponentLen); 
} 

在我係統的輸出是：

Volume Name: Zion 
Serial Number: 112749257 
File System Name: NTFS 
Max Component Length: 255
