Question

我只关心Windows，所以没有必要进入关于Mono兼容性或类似内容的esoterica。

我还应该补充一点，我写的应用程序是WPF，如果可能的话，我宁愿避免依赖System.Windows.Forms。

            }

        }

                q.WithinInterval = new TimeSpan(0, 0, 3);
                q.Condition = "TargetInstance ISA 'Win32_USBControllerdevice'";
                w = new ManagementEventWatcher(scope, q);
                w.EventArrived += USBInserted;

                w.Start();
            }
            catch (Exception e) {

                Console.WriteLine(e.Message);
                if (w != null)
                {
                    w.Stop();

                }
            }

        }

        static void USBInserted(object sender, EventArgs e)
        {

            Console.WriteLine("A USB device inserted");

        }

        static void USBRemoved(object sender, EventArgs e)
        {

            Console.WriteLine("A USB device removed");

        }
    }

使用WMI轮询比执行此操作简单得多 - 只需捕获WM_DEVICECHANGE：

最简单的方法是创建一个自动播放处理程序：

自动播放版本2是一项功能 Windows XP将扫描第一个四个级别的可移动媒体，何时它到了，寻找媒体内容类型（音乐，图形或视频）。申请注册已完成在内容类型的基础上。当一个可移动媒体到来，Windows XP 确定要执行的操作评估内容和比较它是注册处理程序的内容。
