Some nice person built yasnippet.el, a snippet package for emacs. You type 2 or 3 letters, then hit TAB, and it expands into a snippet. Like dabbrev, but with forms-based fill-in fields. It's quickie code generation. Sadly, no C# snippets are included.
Here's my contribution (attached). There's one for try..catch, foreach, for, using, while, class definition, property definition, singleton, and a couple others.
yasnippet worked like a charm for me. I did have to make a change in yasnippet.el:
; added csharp so it will show up in the menu!!
'(ruby-mode rst-mode csharp-mode)
"A list of mode which is well known but not part of emacs.")
Also I built a tool to generate the snippet bundle:
;; Useful utility for creating / updating / maintaining snippets ..
;; Complements the yasnippet package.
;; Run this once, and it creates the bundle.el file.
;; do not delete this file!

; the starting point
; the bundle file to generate
; the snippet dir from which to generate the bundle
