制作一个命令行Rss阅读程序。要求如下：
Write a simple command line RSS reader application that retrieves the last 20 entries from a given RSS Address as a command line argument and displays them. You must not use any external assemblies.
Notes:
1. Your application must actually connect to either RSS Address and retrieve the entries.
2. The connection must not be simulated.
3. Using C#/C++.
4. You must provide the full source code in your answer, and your code must not exceed 200 lines.
A session with your app (RSSReader) can look like this:
-----
C:\Users\someuser> RSSReader http://news.google.com/news?output=rss
Top Stories from news.google.com
1: Yanks' Burnett on target in his World Series debut - USA Today
2: Coast Guard: Navy chopper crashes off Calif. coast - The Associated Press
3: [Blah blah blah]
4: [Blah blah blah]
