The title pretty much says it all. When I'm doing some reflection through my classes, will the MemberInfo.GetCustomAttributes() method preserve the order of attributes on a member, or not?

I've got a legacy database with a bunch of idiotically named columns like: some_field_c some_other_field_c a_third_field_c I would very much like to make a Rails ActiveRecord sub-class that automatically aliases these attributes to their name minus the underscore and "c". However, when I tried: attributes.each_key do | key | name =...
We have this pattern everywhere in our code: using (ServiceAccess ws = new ServiceAccess()) { //... //code here to talk to webservice ws //... } How can I replace this boiler plate code with an attribute on the functions that need to talk to the web service?

It relies heavily on attributes and reflection: the controller looks something like this: [ControllerFor("project")] cla...
This would appear to imply "no". Which is unfortunate.
