您收到一个异常,因为您的 deviceID
包含需要转义的字符(反斜杠).使用简单的替换,您不应该得到异常.
You get an exception because your deviceID
contains characters that need to be escaped (backslashes). With simple replace you shouldn't get the exception.
string query = string.Format("SELECT * FROM Win32_LogicalDisk WHERE DeviceID='{0}'", deviceID.Replace(@"\", @"\\"));
但是,从 WMI 获取 USB 驱动器盘符要复杂一些.您需要学习一些课程,如@MSalters 在评论中发布的链接所述:
However, getting USB drive letter from WMI is a little more complicated. You need to go through a few classes, as stated in a link that @MSalters posted in his comment:
Win32_DiskDrive-> Win32_DiskDriveToDiskPartition -> Win32_DiskPartition -> Win32_LogicalDiskToPartition -> Win32_LogicalDisk.
此处为我工作:
foreach (ManagementObject device in new ManagementObjectSearcher(@"SELECT * FROM Win32_DiskDrive WHERE InterfaceType LIKE 'USB%'").Get())
{
Console.WriteLine((string)device.GetPropertyValue("DeviceID"));
Console.WriteLine((string)device.GetPropertyValue("PNPDeviceID"));
foreach (ManagementObject partition in new ManagementObjectSearcher(
"ASSOCIATORS OF {Win32_DiskDrive.DeviceID='" + device.Properties["DeviceID"].Value
+ "'} WHERE AssocClass = Win32_DiskDriveToDiskPartition").Get())
{
foreach (ManagementObject disk in new ManagementObjectSearcher(
"ASSOCIATORS OF {Win32_DiskPartition.DeviceID='"
+ partition["DeviceID"]
+ "'} WHERE AssocClass = Win32_LogicalDiskToPartition").Get())
{
Console.WriteLine("Drive letter " + disk["Name"]);
}
}
}
