So, I have a nice domain model built. Repositories handle the data access and what not. A new requirements has popped up that indicates that reasons need to be logged with deletes.

Does anyone know if there is a good equivelent to Java's Set collection in C#. It's one of the few things I miss from having moved to C#. I am aware that you can have a "pretend" set using a Dictionary or Hashtable and only bothering to populate the keys. But it's not very elegant.

Say you've loaded a text file into a string and you'd like to convert all unicode escapes into actual unicode characters inside of the string.

Forward is straight forward (sorry) using Properties or maybe parameters in a New() or DoStuff() method, but what about sending something back when the user is done with the second form? (IE.
