.Net KeyEventArgs return vs enter

Question

Have this in a c# .net application:

string key = e.KeyCode.ToString();

in .net 1.1 key = "enter"

in .net 3.5 key = "return"

my question is why are they different?

Answer 1

The Keys enum has identical values for Enter and Return (it also has a number of other duplicates). The framework chose a different value in ToString.

Answer 2

Here are all of the duplicate names: This was generated by the following query in LINQPad:

Enum.GetNames(typeof(Keys))
    .GroupBy(k => Enum.Parse(typeof(Keys), k))
    .Where(g => g.Count() > 1)
    .Select(g => String.Join(", ", g.Select(k => k.ToString()).ToArray()))
