如何在.NET下使用MetaWeBlog API迁移博客

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

See the end of this message for details on invoking 

just-in-time (JIT) debugging instead of this dialog box.

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
