Converting Enums (c#)

Given:

    public enum SomeEnumType : int
    {
        None = 0,
    }

    int b = 0;

why does the following cast succeed:

    SomeEnumType a = (SomeEnumType) b;

while the following conversion fails:

    SomeEnumType a = Convert.ChangeType(b, typeof(SomeEnumType));

Is there a "generic" way of converting integer values into integer-based enums?

with a cast as in your first attempt?
if you really want to use some automatic/reflection way of doing that:
SomeEnumType a = (SomeEnumType)Enum.ToObject(typeof(SomeEnumType), b);

But granted I would take it as bug worth reporting there:

Thank you thank you thank you!! I don't know how I missed that method of Enum, but it neatly solves the problem!
