How to iterate through a collection of enum values?

[Billy Porter]

Greetings,

If I populate an ArrayList with values from, let's say, the Keys enum:

ArrayList a = new ArrayList();
a.Add(Keys.Home);
a.Add(Keys.End);

....then how do I iterate through the collection to see which values it
contains?

Thanks,
Billy

Hi Billy,

string[] allKeys = System.Enum.GetNames(Keys.GetType());
foreach (string s in allKeys)
{
Console.WriteLine(s);
}

Or did you mean something else:

ArrayList al = new ArrayList();
al.Add(DialogResult.OK);
al.Add(DialogResult.No);

foreach (object o in al)
{
Console.WriteLine(System.Enum.Parse(DialogResult.GetType(),
o.ToString()).ToString());
}
