本文實例講述了C#獲取U盤序列號的方法。分享給大家供大家參考。具體如下：
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 30 31 32 33 34 35 36 37 38 39 40 | using System.Management;private List<string> _serialNumber = new List<string>();/// <summary>/// 調用這個函數將本機所有U盤序列號存儲到_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;} |
調用方法：
1 2 3 4 5 6 | matchDriveLetterWithSerial();string[] aa = _serialNumber.ToArray();for (int i = 0; i < aa.Length; i++){ aa[i].ToString(); //這里就可以拿出現在所有的U盤序列號} |
希望本文所述對大家的C#程序設計有所幫助。
