如何打开和关闭CD/DVD驱动器托盘? [英] How to Open and Close CD/DVD Drive Tray ?

问题描述

我环顾四周，找不到想要解决的简单解决方案.

我想从我的C#应用​​程序中打开CD-ROM.它应该检查介质是否实际上是CD-ROM，然后将其打开.

I have looked around and can''t find a simple solution to what I want to do.

I want to open a CD-Rom from my C# app. It should check if the media is in fact a cd- rom and then open it. Is there a quick solution to this or am I missing something?
