Im trying to figure out why the following is making me cast the enumerator.

Here is the enumerator:
public enum SecurityLevel { L1 = 0, L2, L3, L4, L5 }
This code here works but forces me to cast the JSOEnum.Security
JOSEnum.SecurityLevel test = (JOSEnum.SecurityLevel)Enum.Parse(typeof(JOSEnum), "test");
This code does not work because it requires a cast.
JOSEnum.SecurityLevel test = Enum.Parse(typeof(JOSEnum.SecurityLevel), "test");

So my question is, why do I have to cast? Wouldn't the parse function take care of the type?
