How can I create an Activity that encompasses other Activities?

SO. I am starting out in WF4 and I have a design/flow question. I created a custom code activity that takes an "in argument" and stores a result to an "out argument". Pretty basic. Next I use an "If" flow operator using the result of the "out argu开发者_开发技巧ment". All of that works great. But my question is, can I create a custom code activity that combines these two steps together? I looked into extending from the System.Activities.Statements.If class, but the class is sealed. Any suggestions?

Thanks.

It looks like Custom Control Flow. You may find Authoring Custom Control Flow Activities in WF 4 article to be useful.
