Code auto-complete does not work for one specific class

Question

Like the title says, my code isn't auto completing in one specific class in my project which is really terrible for a beginning programmer like me.

I've tried both Ctrl + Alt + Space and going to Tools -> Text Editor -> C# -> IntelliSense. Here "Show completion list after a character is typed" is checked.

Note: Ctrl + Alt + Space does work in other classes, if that is of any help.

The relevant code is:

namespace AudioDevices.Devices
{
    class CdDiscMan : DisplayAudioDevice
    {
        private readonly int mBSize = 700;
        private bool isEjected = false;

        public CdDiscMan(int serialId)
        {
            base.SerialID = serialId;
        }

        public void Eject()
        {
            isEjected = !isEjected;
        }

        public int MbSize
        {
            get { return mBSize; }
        }
        public bool IsEjected
        {
           get { return isEjected; }
        }
    }
}

Upon request, a class in which the auto-complete still functions:

namespace AudioDevices
{

public class Track
{
    private category style;
    private int id;
    private string name, artist, albumSource;
    private Time length;


    public Track()
    {

    }
    public Track(int id)
    {
        this.id = id;
    }
    public Track(int id, string name)
    {
        this.id = id;
        this.name = name;
    }
    public Track(int id, string artist, string name)
    {
        this.id = id;
        this.artist = artist;
        this.name = name;
    }

    public string GetLength()
    {
        return length.ToString();

    }
    public int GetLengthInSeconds()
    {
        return length.Seconds +
            (length.Minutes * 60) +
            (length.Hours * 3600);
    }
}
}

Answer 1

Make sure your namespace is same for both classes.. If yes then restart (quit/start) the visual studio...

Answer 2

I think you either have forgotten to put a semicolon somewhere or you have made a syntax error somewhere. Please post your code so that I can tell you whats the problem.
