易采站长站为您分析C#获取U盘序列号的方法,涉及C#针对硬件底层信息操作的相关技巧,具有一定参考借鉴价值,需要的朋友可以参考下
本文实例讲述了C#获取U盘序列号的方法。。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);
