在网上闲逛，突然对博客的接口感兴趣，经考察，多数博客都对metaWeblog Api 提供了支持，虽然windows live writer是好用，不过出于对这个接口的好奇,也想自己做个能发博客的小工具.
到处浏览资料，用了一个下午终于成功发布了一篇简陋版博客：）。其实很简单，方法对了很快就连上了。
MetaWeblog API中文说明
1、什么是MetaWeblog API？
MetaWeblog API（MWA）是一个Blog程序接口标准，允许外部程序来获取或者设置Blog的文字和熟悉。他建立在XMLRPC接口之上，并且已经有了很多的实现。
2、基本的函数规范
有三个基本的函数规范：
metaWeblog.newPost (blogid, username, password, struct, publish) 返回一个字符串，可能是Blog的ID。
metaWeblog.editPost (postid, username, password, struct, publish) 返回一个Boolean值，代表是否修改成功。
metaWeblog.getPost (postid, username, password) 返回一个Struct。其中blogid、username、password分别代表Blog的id（注释：如果你有两个Blog，blogid指定你需要编辑的blog）、用户名和密码。
一、要引用的DLL【网上提供的示例多包含了这个DLL】
二、要实现的数据结构
