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。
