Maintain a class with dictionary of properties

I need to design a class where each of the properties of the class is added and updated in an ObservableDictionary.

Here is the code I have come up with.

class Win32_DiskDrive : INotifyPropertyChanged
{
    private readonly string _classname = "Win32_DiskDrive";

    public string ClassName
    {
        get
        {
            return _classname;
        }
    }

    private string _caption;

    public string Caption
    {
        get
        {
            return _caption;
        }

        set
        {
            if ((value != _caption) || (value != null))
            {
                _caption = value;
                UpdateDictionary();
                OnPropertyChange();
            }
        }
    }

    private string _serialNo;

    public string SerialNumber
    {
        get
        {
            return _serialNo;
        }
        set
        {
            if ((value != _serialNo) || (value != null))
            {
                _serialNo = value;
                UpdateDictionary();
                OnPropertyChange();
            }
        }
    }

    private IDictionary<string,string> _diskDriveProperties = new ObservableDictionary<String, String>();

    public IDictionary<string, string> PropertiesDictionary
    {
        get
        {
            return _diskDriveProperties;
        }

        set
        {
            _diskDriveProperties = value;
        }
    }

    private void UpdateDictionary([CallerMemberName] string propertyname = null)
    {
        _diskDriveProperties[propertyname] = this.GetType().GetProperty(propertyname).GetValue(this).ToString();
    }

    public event PropertyChangedEventHandler PropertyChanged;

    private void OnPropertyChange([CallerMemberName] string propertyname = null)
    {
        PropertyChanged?.Invoke(this, new PropertyChangedEventArgs(propertyname));
    }
}

What I have tried:

My implementation uses reflection to update the Dictionary. Is there a way to implement this class without reflection by using Linq?
