如何在C＃的下拉框中列出CD驱动器 [英] How do I list CD drive in a dropdown box in C#

问题描述

我是C＃的新手，我目前正在做一个项目。当找到包含数据的光盘时，我需要能够在下拉列表中列出CD驱动器。你怎么做到这一点？？请帮忙我难倒!!



我尝试过：



private void ReloadDrives（）//下拉框

{



Cbo1.DataSource = Environment.GetLogicalDrives（）;



var drives =来自DriveInfo.GetDrives（）中的驱动器//获取可移动驱动器

其中Drive.DriveType == DriveType.Removable

选择云端硬盘; //列出组合框中的驱动器



Cbo1.DataSource = drives.ToList（）; //列出组合框中的驱动器

}

I am new to C# and I am currently doing a project. I need to be able to list the cd drive in a drop down list when a disc is found with data on it. How do you do this?? Please help i'm stumped!!

What I have tried:

private void ReloadDrives() // Drop down box
{

Cbo1.DataSource = Environment.GetLogicalDrives();

var drives = from Drive in DriveInfo.GetDrives() // gets removable drives
where Drive.DriveType == DriveType.Removable
select Drive; // lists drives in the combobox

Cbo1.DataSource = drives.ToList(); //lists drives in combobox
}

推荐答案

首先我认为您需要使用 DriveType.CDRom 而不是 DriveType.Removable 。

然后你需要从驱动器中获取文件，例如

Firstly I think you need to be using DriveType.CDRom rather than DriveType.Removable.
You then need to get the files from the drive e.g.

Cbo1.DataSource = Directory.GetFiles(drives.ToList()[0].Name); 

如果设备未准备就绪，您需要包含一些错误处理

You'll need to include some error handling in case the device is not ready
