C# 讀取U碟序號進行驗證的範例程式碼

C# 读取U盘序列号进行验证的示例代码

private List<string> _serialNumber = new List<string>();

        public void matchDriveLetterWithSeral()
        {
            _serialNumber.Clear();
            string[] diskArray;
            string driveNumber;
            var searcher = new ManagementObjectSearcher("select * from Win32_LogicalDiskToPartition");
            foreach (ManagementObject dm in searcher.Get())
            {
                getValueInQuotes(dm["Dependent"].ToString());
                diskArray = getValueInQuotes(dm["Antecedent"].ToString()).Split(&#39;,&#39;);
                driveNumber = diskArray[0].Remove(0, 6).Trim();
                var disks = new ManagementObjectSearcher("select * from Win32_DiskDrive");
                foreach (ManagementObject disk in disks.Get())
                { 
                    if(disk["Name"].ToString()==("\\\\.\\PHYSICALDRIVE"+driveNumber)&&disk["InterfaceType"].ToString()=="USB")
                    {
                        _serialNumber.Add(parseSerialFromDeviceID(disk["PNPDeviceID"].ToString()));
                    }
                }
            }
        }
