该错误表示该内容.这意味着该类或名称空间不存在.如果您不知道如何解决，那么从网络上复制和粘贴随机代码只会对您不利.首先学习基础编程，然后这里的文章对您很有用.

另外，文章下方有一个论坛可以向作者寻求帮助.

The error means what it says. It means that the class or namespace does not exist. If you don''t know how to work that out, copying and pasting random code from the web can only end badly for you. Learn basic programming first, then the articles here will be of great use to you.

Also, there''s a forum under the article to ask the author for help.
