Lecture du numéro de série du périphérique USB en C#

Question

Existe-t-il un moyen de lire le numéro de série et les données d'un périphérique USB dans un fichier texte USB via visual studio 2005?

Answer 1

Essayez ceci:

USBSerialNumber usb = new USBSerialNumber(); 
string serial = usb.getSerialNumberFromDriveLetter("f:\"); 
MessageBox.Show(serial); 

est ici les entrailles de la classe USBSerialNumber:

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; 
     } 

    } 
}

Ou bien, vous pouvez le faire avec beaucoup moins de code, voici l'échantillon :

 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 réponse est presque juste, mais vous devez passer la lettre de lecteur sans barre oblique inverse dans la fonction: chaîne serial = usb.getSerialNumberFromDriveLetter ("f:");
