Using reflection to find constants

[Mark]

Is there a way using reflection to interrogate a .dll and identify all the
declared constants, as well as their initial values?

Thanks in advance.

Mark,

You should be able to get all of the static fields on a type, and then
cycle through them, checking the IsLiteral property on the FieldInfo
instance representing the field. If IsLiteral returns true, then it is a
constant. To get the value, you can just call GetValue on the FieldInfo
instance, passing null for the instance, and it should return the value of
the constant.

Hope this helps.

Yes.

- Load the assembly (Assembly.Load[From])
- Get all types (Assembly.GetTypes)
- Get all static fields in each type (Type.GetFields)
- Check if it's a const (FieldInfo.Attributes has Literal set)
- If so retrieve the value (FieldInfo.GetValue)
