[myoe] Why there's no priority of mail?

[Weber W. <web...@ho...>]

I found the mail priority is not contained in MyOE, it's a necessory 
property of a mail I think, add it just by a enum field in MessageItem, can 
use a enum by simple, and can use a typesafed enum for more flexible, the 
typesafed enum I write here:
public sealed class MailPriority
{
	private MailPriority(string title, int value)
	{
		this.title = title;
		this.value = value;
	}

	public string Title
	{
		get
		{
			return title;
		}
	}

	public int Value
	{
		get
		{
			return value;
		}
	}

	public static MailPriority[] GetValues()
	{
		MailPriority[] ps = new MailPriority[]
			{
				Highest, 
				High, 
				Normal, 
				Low, 
				Lowest, 
			};
		return ps;
	}

	public override string ToString()
	{
		return title;
	}

	private readonly string title;
	private readonly int value;

	public static readonly MailPriority Highest = new MailPriority("Highest", 
1);
	public static readonly MailPriority High = new MailPriority("High", 2);
	public static readonly MailPriority Normal = new MailPriority("Normal", 
3);
	public static readonly MailPriority Low = new MailPriority("Low", 4);
	public static readonly MailPriority Lowest = new MailPriority("Lowest", 
5);
}
This is a sealed class and the instance of this class is readonly object, 
so needn't thinking of multithread problem and needn't clone object, it's 
more safe, and easy to use.
Best wishes.
