DriveInfo 类的属性

Question

C#USBDriveType

Answer 1

手机相机一般也识别为Removable 1
打印机根本不会被视作"driver"，也不会有盘符，哪里来的类型

Answer 2

你根本用GetDrivers都取不到，你得用wmi去取。

Answer 4

SelectQuery进行WMI查询，是不是Select里面查的是所有驱动器的盘符，应该怎么改才能查到打印机的驱动

driveinfo这个类不行，那哪个类能识别出打印机之类的设备呢

Answer 7

1.windos API
2.WMI
比如：
stringwmiSQL ="SELECT * FROM Win32_Printer";
ManagementObjectCollectionprinters =newManagementObjectSearcher(wmiSQL).Get();driveinfo和
printer不同
