Hi guys,

Maybe someone can explain thisi have this enum:

public enum LimitType : int
{
BottomLimit,
TopLimit,
Limit

}

In another class i read values from my db and cast them to the enum, where
my db id is 1, it will match the enum that is first and so on:

pt = (myClass.LimitType )int.Parse(limitType);

Here is the weird bit, if limitType is a 1, pt becomes BottomLimit. Correct.
if it is a 2 it becomes TopLimit. Correct.
if it is a 3, it becomes the integer 3. Wrong!?

I thought maybe limit is some kind of keyword to the compiler, so i changed
the enum to this:

public enum LimitType : int
{
BottomLimit,
TopLimit,
Limit,
test

}

Ran it again and in debug this happened:

if limitType is a 1, pt becomes BottomLimit. Correct.
if it is a 2 it becomes TopLimit. Correct.
if it is a 3, it becomes test !? Wrong.

Can anyone explain why it seems to be choosing to skip Limit as though it
isn't there? In debug when i check the enum at runtime it does have Limit as
one of the enums and it is in that order. Look forward to the replies.

The part I don't understand is why 1 becomes BottomLimit and 2 becomes
TopLimit, since by default, enums start numbering at 0, not 1. You can
make sure that the values are the ones you want by doing this:

public enum LimitType : int
{
BottomLimit = 1,
TopLimit = 2,
Limit = 3
}

.
