CodeProject:免费开源代码交流社区是一个由软件开发和设计人员组成的一个分享免费开源编程代码的社区网站，用户可以在这里学习、分享、探讨有关于软件编程方面的话题。

MSDN主要是开发文档，技术文章和函数使用示例代码，开发工程中遇到不懂得函数之类的可以及时到MSDN查询，MSDN侧重于开发;而CodeProject 主要是开源代码,上面有很多高手写好的代码可以借鉴，CodeProject侧重于应用。

CodeProject社区拥有成千上万的编程文章和编程教程，汇集世界各地的优秀编程开发人员，如果你是学习编程的用户恰好英语也很厉害，那么在这个社区混绝对能够提高你的编程开发能力。

The Code Project Share your code, libraries, tips and answers to help others and learn from the best. Just need code? Help yourself to 35,003 free Software development and Design articles, tips and downloads.

CodeProject is a community of Software development and Design developers joined together with certain common goals: to learn, to teach and to have fun programming. Developers from all over the world come together to share source code, tutorials and knowledge for free to help their fellow programmers.

It is our hope that you find CodeProject to be a wealth of information and a valuable resource. All we ask is that if you find CodeProject useful, then please share what source code or knowledge you can in order to give back to the community.

Above and beyond articles and code snippets, CodeProject gives developers a voice. We have over 3.5 million people reading CodeProject each month, including those from companies such as Microsoft, Sun, Oracle, and more. CodeProject brings industry and the developer community together.
