新建了个网站，想把之前所有的博客都迁移过去。
学习进行的很顺利，就在我开始测试另外一个博客vwww.aboutdnn.net时，一个错误出现了：
服务器总是报告"Conversion from string "" to type 'Integer' is not valid"，对于这个出错，我很是费解，一样的代码，为什么换了一个博客就开始出问题呢？Rich Strahl 的一篇文章解答了我的问题： MetaWebLog API and Blog Writers

这里有一个library：
Joe Blogs
在codeplex上也有一个：Joe Blogs
这个library完整的实现了对WordPress 的API，同时也支持MetaWeblog API，所以也可以用来处理MetaWeblog API
