Question

public static string GetDriveType()
{
    DriveInfo[] allDrives = DriveInfo.GetDrives();

    foreach (DriveInfo drive in allDrives) 
    {
        return DriveInfo.DriveType;

        if(DriveType.CDRom)
        {
            return DriveInfo.Name;
        }
    }
}

正如大家们可能看到的，这段代码有点不对劲。基本上，我试图返回驱动器的名称，以便稍后在代码中使用，但前提是该驱动器是CDRom驱动器。我怎样才能检查驱动器的名称并将其返回，以便以后在我以编程方式打开CD驱动器时可以解释它？谢谢！

Answer 1

如果有更多CD驱动器，您应该返回一个字符串列表：

public static List<string> GetCDDrives()
{
    var cdDrives =  DriveInfo.GetDrives().Where(drive => drive.DriveType == DriveType.CDRom);

    return cdDrives?.Select(drive => drive.Name).ToList();
}

Answer 2

我认为您需要以下内容：

public static string GetCDRomName()
{
    // Get All drives
    var drives = DriveInfo.GetDrives();
    var cdRomName = null;

    // Iterate though all drives and if you find a CdRom get it's name 
    // and store it to cdRomName. Then stop iterating.
    foreach (DriveInfo drive in allDrives) 
    {
        if(drive.DriveType == DriveType.CDRom)
        {
            cdRomName = drive.Name;
            break;
        }
    }

    // If any CDRom found returns it's name. Otherwise null.
    return cdRomName;
}
