如何检测USB驱动器已插入？ [英] How to detect a USB drive has been plugged in?

问题描述

我想构建一个程序来检测是否插入了一个USBb
（并将所有内容复制到硬盘上的任何文件夹）。

I want to build a program that detects if a usb (or two or more) are plugged in (and copy all contents to any folder on a hard disk)

任何想法？我有这个，

using System.Runtime.InteropServices;

但这不是简单的方法（我相信）。我想要一些容易的东西

But it is not the easy way (that I believe). I want something easy.

我有另一个想法（if（文件夹存在）然后复制）某些东西 - 但可能有问题，我想要一个很好的解决方案。

I have another idea (if (folder exist) then copy) something -- but there may be a problem with that, and I want a good solution.

也可能有一个名为SerialPort的工具;我可以用吗如果是这样，我该如何使用？

There may also be a tool called SerialPort; can I use it? If so, how do I use it?

推荐答案

容易检查可移动设备，但不能保证它是一个USB设备：

It is easy to check for removable devices, however it doesn't guaranty that it is an USB device:

var drives = DriveInfo.GetDrives()
    .Where(drive => drive.IsReady && drive.DriveType == DriveType.Removable);

这将返回当前可访问的所有可移动设备的列表。更多信息：

This will return a list of all removable devices that are currently accessible. More information:

• DriveInfo class （msdn文档）


• DriveType 枚举 （msdn文档）

• The DriveInfo class (msdn documentation)
• The DriveType enumeration (msdn documentation)
