返回用于唯一标识磁盘卷的十进制序列号。

object.SerialNumber 

object 始终是 Drive 对象。

说明

可使用 SerialNumber 属性确保在用于安放可移动媒体的驱动器中插入了正确的磁盘。

以下代码说明了 SerialNumber 属性的用法：

[JScript]
function ShowDriveInfo(drvpath){
  var fso, d, s, t;
  fso = new ActiveXObject("Scripting.FileSystemObject");
  d = fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName(drvpath)));
  switch (d.DriveType)
  {
    case 0: t = "Unknown"; break;
    case 1: t = "Removable"; break;
    case 2: t = "Fixed"; break;
    case 3: t = "Network"; break;
    case 4: t = "CD-ROM"; break;
    case 5: t = "RAM Disk"; break;
  }   
  s = "Drive " + d.DriveLetter + ": - " + t;
  s += "<br>" + "SN: " + d.SerialNumber;
  return(s);
}
[VBScript]
Function ShowDriveInfo(drvpath)
   Dim fso, d, s, t
   Set fso = CreateObject("Scripting.FileSystemObject")
   Set d = fso.GetDrive(fso.GetDriveName(fso.GetAbsolutePathName(drvpath)))
   Select Case d.DriveType
      Case 0: t = "Unknown"
      Case 1: t = "Removable"
      Case 2: t = "Fixed"
      Case 3: t = "Network"
      Case 4: t = "CD-ROM"
      Case 5: t = "RAM Disk"
   End Select
   s = "Drive " & d.DriveLetter & ": - " & t
   s = s & "<BR>" & "SN: " & d.SerialNumber
   ShowDriveInfo = s
End Function
