获取U盘ID序列号 VS2005编译通过，源码源自CSDN。已经测试好用。 可以获得U盘名称，制造商ID号 版本号 U盘序列号及容量 Form1.cs using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Text; using System.Windows.Forms; using System.IO; using System.Management; namespace UDiskTest { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button2_Click(object sender, EventArgs e) { DriveInfo[] s = Dri veInfo.GetDrives(); foreach (DriveInfo drive in s) { if (drive.DriveType == DriveType.Removable) { pf.Text = drive.Name.ToString(); break; } } ManagementClass cimobject = new ManagementClass("Win32_DiskDrive"); ManagementObjectCollection moc = cimobject.GetInstances(); foreach (ManagementObject mo in moc) { if (mo.Properties["InterfaceType"].Value.ToString() == "USB") { try { //产品名称 Caption.Text = mo.Properties["Caption"].Value.ToString(); //总容量 Size.Text = mo.Properties["Size"].Value.ToString(); string[] info = mo.Properties["PNPDeviceID"].Value.ToString().Split('&'); string[] xx = info[3].Split('\\'); //序列号 MessageBox.Show("U盘序列号:" + xx[1]); PNPDeviceID.Text = xx[1]; xx = xx[0].Split('_'); //版本号 REV.Text = xx[1]; //制造商ID xx = info[1].Split('_'); VID.Text = xx[1]; } catch (Exception ex) { MessageBox.Show(ex.Message); } } } } } } 如果编译遇到问题是using System.Management;无法找到引用找到， 项目(p)->添加引用(R)->找到.NET标签页 列表中下部位找到System.Management 双击点确定
