本文实例讲述了C#获取U盘序列号的方法。分享给大家供大家参考。具体如下：
using System.Management; private List<string> _serialNumber = new List<string>(); /// <summary> /// 调用这个函数将本机所有U盘序列号存储到_serialNumber中 /// </summary> private void matchDriveLetterWithSerial() { 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(','); 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())); } } } } private static string parseSerialFromDeviceID(string deviceId) { var splitDeviceId = deviceId.Split(''); var arrayLen = splitDeviceId.Length - 1; var serialArray = splitDeviceId[arrayLen].Split('&'); var serial = serialArray[0]; return serial; } private static string getValueInQuotes(string inValue) { var posFoundStart = inValue.IndexOf("""); var posFoundEnd = inValue.IndexOf(""", posFoundStart + 1); var parsedValue = inValue.Substring(posFoundStart + 1, (posFoundEnd - posFoundStart) - 1); return parsedValue; }
调用方法：
matchDriveLetterWithSerial(); string[] aa = _serialNumber.ToArray(); for (int i = 0; i < aa.Length; i++) { aa[i].ToString(); //这里就可以拿出现在所有的U盘序列号 }
希望本文所述对大家的C#程序设计有所帮助。
