如何检测时，使用C＃插入移动硬盘？ [英] How do I detect when a removable disk is inserted using C#?

问题描述

我只是担心Windows系统，因此没有必要进入有关单声道兼容性或任何类似的秘籍。

I'm just concerned about Windows, so there's no need to go into esoterica about Mono compatibility or anything like that.

我还要补充一点，我正在写的应用程序是WPF，和我preFER避免服用对 System.Windows.Forms的依赖如果在所有可能的。

I should also add that the app that I'm writing is WPF, and I'd prefer to avoid taking a dependency on System.Windows.Forms if at all possible.

给这个一杆...

using System;
using System.Collections.Generic;
using System.Text;
using System.Management;

namespace WMITestConsolApplication
{

    class Program
    {

    	static void Main(string[] args)
    	{

    		AddInsertUSBHandler();
    		AddRemoveUSBHandler();
    		while (true) {
    		}

    	}

    	static ManagementEventWatcher w = null;

    	static void AddRemoveUSBHandler()
    	{

    		WqlEventQuery q;
    		ManagementScope scope = new ManagementScope("root\\CIMV2");
    		scope.Options.EnablePrivileges = true;

    		try {

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

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


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

    			}
    		}

    	}

    	static void AddInsertUSBHandler()
    	{

    		WqlEventQuery q;
    		ManagementScope scope = new ManagementScope("root\\CIMV2");
    		scope.Options.EnablePrivileges = true;

    		try {

    			q = new WqlEventQuery();
    			q.EventClassName = "__InstanceCreationEvent";
    			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");

    	}
    }

}
