There isn't a [Enum].TryParse, but there is [Enum].IsDefined which if try means your [Enum].Parse should succeed.

You should also be able to add a None = -1 option to the Enum

In my enums I tend to use a pattern like:

public enum Items
{
    Unknown = 0,
    One,
    Two, 
    Three,
}

So that a default int -> Enum will return Unknown

Edit - Oh, looks like there is a TryParse in .Net 4. That's neat!
