这篇文章主要介绍了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。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

}
