Getting the number of items in a enum

UJ
Is there a way to get the number of items that are in an enum? I'm trying to
find out how many items there are so that I can hit every one of them to
test.

TIA - Jeff.

Look at Enum.GetValues and Enum.GetNames.

enum Colors { Red, Green, Blue, Yellow };

foreach(string s in Enum.GetNames(t ypeof(Colors)))
Console.WriteLi ne(s);

There is also a GetValues(..)

Enum.GetNames/GetValues is necessary as everyone hs said but might not be
sufficient because:

1) Duplicate values are allowed. This isn't really a problem but you might
want to weed out duplicate values.

2) The enum might have the FlagsAttribute in which case you need to OR
together all possible combinations.

Hi, I'm a newbie to programming of any kind. I have posted this to other groups in a hope to get a response from anyone. Can any one tell me how to make my VB program read the Bios serial number (or would HDD be better, or both?) and put that info into VB prog so the program won't work on another computer. My program uses an MSAccess table. Much appreciated if you can help! Thanks

Say that I create a combobox with pull down items that map directly to an enum.
