C#获取U盘序列号的方法

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。
