Combined Enums / [Flags]

[Rain]

Im using C#3.0 and in my book of words it tells me that when I use the
[Flags] I should be able to call ToString() on a combined enumeration and
have it emit a series of strings.

IE

[Flags]
public enum myEnum
{

left =1,
right=2,
leftright = left | right

}

console.write ( myEnum.toString() ) // I Get LeftRight, when my book says I
should get "left, right"

Is the book incorrect ?

Cheers

No. In your example, "left | right" and "leftright" have identical
numeric values, so it picks the one that has a name in the enum. If the
combination with | operator doesn't (numerically) equal a value in the
enum, you will get the comma-separated string you mentioned instead.

Eq.

Ahhh.

So simple, yet I didnt spot it.
Thank you.
