使用c#进行便携式设备检测

本文关键字：检测 便携式 使用 | 更新日期: 2023-09-27 18:09:01

我在检测便携式设备时遇到了问题，特别是三星手机或iphone。我需要开发一个程序，一旦检测到便携式插件就会启动，一旦拔掉就会停止。

我一直在尝试这个代码，但只适用于带有存储的usb设备，而不是便携式设备。

private void DeviceInsertedEvent(object sender, EventArrivedEventArgs e)
{
    ManagementBaseObject instance = (ManagementBaseObject)e.NewEvent["TargetInstance"];
    foreach (var property in instance.Properties)
    {
        Console.WriteLine(property.Name + " = " + property.Value);
    }
}
void DeviceRemovedEvent(object sender, EventArrivedEventArgs e)
{
    ManagementBaseObject instance = (ManagementBaseObject)e.NewEvent["TargetInstance"];
    foreach (var property in instance.Properties)
    {
        Console.WriteLine(property.Name + " = " + property.Value);
    }
}            
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
    WqlEventQuery insertQuery = new WqlEventQuery("SELECT * FROM __InstanceCreationEvent WITHIN 2 WHERE TargetInstance ISA 'Win32_USBHub'");
    ManagementEventWatcher insertWatcher = new ManagementEventWatcher(insertQuery);
    insertWatcher.EventArrived += new EventArrivedEventHandler(DeviceInsertedEvent);
    insertWatcher.Start();
    WqlEventQuery removeQuery = new WqlEventQuery("SELECT * FROM __InstanceDeletionEvent WITHIN 2 WHERE TargetInstance ISA 'Win32_USBHub'");
    ManagementEventWatcher removeWatcher = new ManagementEventWatcher(removeQuery);
    removeWatcher.EventArrived += new EventArrivedEventHandler(DeviceRemovedEvent);
    removeWatcher.Start();
    // Do something while waiting for events
    System.Threading.Thread.Sleep(20000000);
}

请帮助。由于

使用c#进行便携式设备检测

你试过了吗:

System.IO.DriveInfo [] drives = System.IO.DriveInfo.GetDrives ();
foreach (System.IO.DriveInfo drive in drives)
{
  if (drive.DriveType == DriveType.Removable)
  {
    Console.WriteLine ("Found removable drive {0}", drive.Name);
  }
}
