How to apply InterLocked.Exchange for Enum Types in C#?

Question

public enum MyEnum{Value1, Value2}  
class MyClass 
{ 
    private MyEnum _field;   
    public MyEnum Field  // added for convenience
    {
        get { return _field;

Is there any better way for this problem?

I use a class instead of Enum:

public class DataCollectionManagerState
{
    public static readonly DataCollectionManagerState Off = new DataCollectionManagerState() { };
    public static readonly DataCollectionManagerState Starting = new DataCollectionManagerState() { };
    public static readonly DataCollectionManagerState On = new DataCollectionManagerState() { };

    private DataCollectionManagerState() { }

    public override string ToString()
    {
        if (this == Off) return "Off";
        if (this == Starting) return "Starting";
        if (this == On) return "On";

        throw new Exception();
    }
}

public class DataCollectionManager
{
    private static DataCollectionManagerState _state = DataCollectionManagerState.Off;

    public static void StartDataCollectionManager()
    {
        var originalValue = Interlocked.CompareExchange(ref _state, DataCollectionManagerState.Starting, DataCollectionManagerState.Off);
        if (originalValue != DataCollectionManagerState.Off)
        {
            throw new InvalidOperationException(string.Format("StartDataCollectionManager can be called when it's state is Off only. Current state is \"{0}\".", originalValue.ToString()));
        }

        // Start Data Collection Manager ...

        originalValue = Interlocked.CompareExchange(ref _state, DataCollectionManagerState.On, DataCollectionManagerState.Starting);
        if (originalValue != DataCollectionManagerState.Starting)
        {
            // Your code is really messy
            throw new Exception(string.Format("Unexpected error occurred. Current state is \"{0}\".", originalValue.ToString()));
        }
    }
}
