USB 设备已连接 [英] USB Device Connected

问题描述

我正在尝试创建一个函数，根据设备的 pid 和 vid，检测 USB 设备是否已连接.我希望它看起来像这样，我只是不知道如何在 C# 中做到这一点.

I'm trying to make a function that detects if a usb device is connected given the devices pid and vid. I'm hoping it would look something like this, I'm just not sure how to do this in C#.

public bool IsUsbDeviceConnected(string pid, string vid)
{
  //Code here
}

推荐答案

//using System.Management
public bool IsUsbDeviceConnected(string pid, string vid)
{   
  using (var searcher = 
    new ManagementObjectSearcher(@"Select * From Win32_USBControllerDevice"))
  {
    using (var collection = searcher.Get())
    {
      foreach (var device in collection)
      {
        var usbDevice = Convert.ToString(device);

        if (usbDevice.Contains(pid) && usbDevice.Contains(vid))
          return true;
      }
    }
  }
  return false;
}
