USB設備連接

Question

我試圖做一個功能，檢測是否USB設備連接給定的設備PID和VID。我希望它看起來像這樣，我只是不知道如何在C＃中做到這一點。

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

Answer 1

//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; 
}

可能類似於

//import the System.Management namespace at the top in your "using" statement. Then in a method, or on a button click: 

ManagementObjectCollection collection; 
using (ManagementObjectSearcher searcher = new ManagementObjectSearcher("SELECT * FROM Win32_DiskDrive WHERE InterfaceType='USB'")) 
    collection = searcher.Get(); 
foreach (ManagementObject currentObject in collection) 
{ 
    ManagementObject theSerialNumberObjectQuery = new ManagementObject("Win32_PhysicalMedia.Tag='" + currentObject["DeviceID"] + "'"); 
    MessageBox.Show(theSerialNumberObjectQuery["SerialNumber"].ToString()); 
} 
collection.Dispose(); 

使用WMI
