Read USB Device Serial number in C#
提问by rahul
Is there a way to read USB device serial number and data in a text file in USB using visual studio 2005?
有没有办法使用visual studio 2005读取USB中的文本文件中的USB设备序列号和数据？

Try this:
尝试这个：
USBSerialNumber usb = new USBSerialNumber();
string serial = usb.getSerialNumberFromDriveLetter("f:\");
MessageBox.Show(serial);
Here's the internals for the USBSerialNumber class:
这是 USBSerialNumber 类的内部结构：
using System;
using System.Collections.Generic;
using System.Text;
using System.Management;
namespace USBDriveSerialNumber {
public class USBSerialNumber {
string _serialNumber;
string _driveLetter;
public string getSerialNumberFromDriveLetter(string driveLetter) {
this._driveLetter = driveLetter.ToUpper();
if(!this._driveLetter.Contains(":")) {
this._driveLetter += ":";
}
matchDriveLetterWithSerial();
return this._serialNumber;
}
private void matchDriveLetterWithSerial() {
string[] diskArray;
string driveNumber;
string driveLetter;
ManagementObjectSearcher searcher1 = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDiskToPartition");
foreach (ManagementObject dm in searcher1.Get()) {
diskArray = null;
driveLetter = getValueInQuotes(dm["Dependent"].ToString());
diskArray = getValueInQuotes(dm["Antecedent"].ToString()).Split(',');
driveNumber = diskArray[0].Remove(0, 6).Trim();
if(driveLetter==this._driveLetter){
/* This is where we get the drive serial */
ManagementObjectSearcher disks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive");
foreach (ManagementObject disk in disks.Get()) {
if (disk["Name"].ToString() == ("\\.\PHYSICALDRIVE" + driveNumber) & disk["InterfaceType"].ToString() == "USB") {
this._serialNumber = parseSerialFromDeviceID(disk["PNPDeviceID"].ToString());
}
}
}
}
}
private string parseSerialFromDeviceID(string deviceId) {
string[] splitDeviceId = deviceId.Split('\');
string[] serialArray;
string serial;
int arrayLen = splitDeviceId.Length-1;
serialArray = splitDeviceId[arrayLen].Split('&');
serial = serialArray[0];
return serial;
}
private string getValueInQuotes(string inValue) {
string parsedValue = "";
int posFoundStart = 0;
int posFoundEnd = 0;
posFoundStart = inValue.IndexOf("\"");
posFoundEnd = inValue.IndexOf("\"", posFoundStart + 1);
parsedValue = inValue.Substring(posFoundStart + 1, (posFoundEnd - posFoundStart) - 1);
return parsedValue;
}
}
}

Or, you can do it with much less code, here's the sample:
或者，您可以使用更少的代码来完成，这是示例：
string driveletter = "D:";
var index = new ManagementObjectSearcher("SELECT * FROM Win32_LogicalDiskToPartition").Get().Cast<ManagementObject>();
var disks = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive").Get().Cast<ManagementObject>();
string serial = "";
try
{
var drive = (from i in index where i["Dependent"].ToString().Contains(driveletter) select i).FirstOrDefault();
var key = drive["Antecedent"].ToString().Split('#')[1].Split(',')[0];
var disk = (from d in disks
where
d["Name"].ToString() == "\\.\PHYSICALDRIVE" + key &&
d["InterfaceType"].ToString() == "USB"
select d).FirstOrDefault();
serial = disk["PNPDeviceID"].ToString().Split('\').Last();
}
catch
{
//drive not found!!
}
Response.WriteLine(serial);

Matt answer is almost right, but you must pass drive letter without back slash in function: string serial = usb.getSerialNumberFromDriveLetter("f:");
马特答案几乎是正确的，但您必须在函数中传递驱动器号而不带反斜杠： string serial = usb.getSerialNumberFromDriveLetter(" f:");
