为您的项目添加对System.Management的引用，然后尝试执行以下操作：
namespace ConsoleApplication1{ using System; using System.Collections.Generic; using System.Management; // need to add System.Management to your project references. class Program { static void Main(string[] args) { var usbDevices = GetUSBDevices(); foreach (var usbDevice in usbDevices) { Console.WriteLine("Device ID: {0}, PNP Device ID: {1}, Description: {2}", usbDevice.DeviceID, usbDevice.PnpDeviceID, usbDevice.Description); } Console.Read(); } static List<USBDeviceInfo> GetUSBDevices() { List<USBDeviceInfo> devices = new List<USBDeviceInfo>(); ManagementObjectCollection collection; using (var searcher = new ManagementObjectSearcher(@"Select * From Win32_USBHub")) collection = searcher.Get(); foreach (var device in collection) { devices.Add(new USBDeviceInfo( (string)device.GetPropertyValue("DeviceID"), (string)device.GetPropertyValue("PNPDeviceID"), (string)device.GetPropertyValue("Description") )); } collection.Dispose(); return devices; } } class USBDeviceInfo { public USBDeviceInfo(string deviceID, string pnpDeviceID, string description) { this.DeviceID = deviceID; this.PnpDeviceID = pnpDeviceID; this.Description = description; } public string DeviceID { get; private set; } public string PnpDeviceID { get; private set; } public string Description { get; private set; } }}
