使用C#转移Wordpress博客到为知笔记或Evernote的方法

文中的方法非常简单，使用MySQL导出表到XML，发送邮件到你的为知/Evernote邮箱账户即可，唯一目前没找到破的是SMTP常随机无响应，而且象GMAIL的SMTP有发送次数限制（一天一千左右吧，所以如果有超过的话可能需要更换账号再试，当然你也可以改良下，做个数组，遇到配额错误可以提取下一个SMTP信息），优点是利用邮件的方式可以将博客中的图片也能导入到笔记中（而不是用的图片原链接，是直接放进笔记）
日志导入Wiz的结果：
一、目的
很简单，我担心博客放在网上有一天会不见了，所以一直想存到本地，博客太多，手动已不可能
我这些年使用wordpress有上千篇博客，其中有8成都是私有，使用现在的一些读取FEED方式导出的方式不能读取私有和保护博客，Wordpress也有导出插件，我没有试太多，有一个导出xml的工具采用流式试过十多次没有一次是完整导出，有时导出100来K，有时几M，之后放弃使用WP插件导出。
数据源：使用MySQL导出XML。
首先原因是空间提供商不提供MySQL远程连接，（如果你能导出SQL在本地建MySQL再导入，就不在这个话题范围内）。我原本想导出为SQL，再转换为MSSQL，可在网上找的所有converter都是必须登陆远程MySQL服务器，这条路径也行不通。导出的CSV为乱码，试过UTF8, GB2312都不行，这条路径也行不通。之后发现只有导出XML时没有乱码。这就简单多了。
使用C#读取XML时，有几类重要的信息是个人觉得必需的
博客表 wp_posts
类别(category / tag等) 表wp_term_taxonomy, wp_terms wp_term_relationships
SQL： 
-- 列出全部日志 --
create view v_post as
SELECT p.*, tax.term_taxonomy_id,tax.term_id,category.name, tax.count
FROM
wp_term_relationships relation,
wp_terms category,
wp_term_taxonomy tax,
wp_posts p
WHERE
category.term_id = tax.term_id and
tax.term_taxonomy_id = relation.term_taxonomy_id and
relation.object_id = p.id

二、操作步骤
登陆你空间的phpAdmin，选中日志数据库后，选择Export，框选的是需要注意的，导出时不要选择导出TABLE/VIEW等SQL语句。UTF-8必选否则会有乱码
得到导出的XML将作为我们的数据源。请一定确保下载下来的XML是有效的（我刚试过，这一种也有可能会下载不完整，无解 /摊手）

三、可改善的地方
Mail body顶部，我加入了日志详情
我没有将日志放进tag，你可以改一下代码使之subject上加入tag (for evernote, 加入#tag1 tag2等，自行查下规则）
唯一目前没找到破的是SMTP常随机无响应.. 你如果找到可以破的（比如CATCH到IOExeption重连的），麻烦告诉我
GMAIL的SMTP有发送次数限制（一天一千左右吧，所以如果有超过的话可能需要更换账号再试，当然你也可以改良下，做个数组，遇到配额错误可以提取下一个SMTP信息） 四、关于为知Wiz
个人觉得Wiz是个还有很多提升空间的、自定义性比较强的国产笔记类软件，记得用Wiz的话一定要注意给你不愿意别人看到的条目加个密，不然按Wiz的目录式的HTML文件在电脑中完全没有秘密可言，知道目录的无需登陆就能打加所有日志。
没有Wiz账号的，在这顺便递送个邀请码吧，6d485186 (http:// .wiz.cn/i/?6d485186)，据说用了注册后第一个月有VIP试用，当然你不用也行。
比较起Evernote来说，好处就是日志的空间比较大，插件化让它比较有趣味。 比如它可以导出CHM，可以把以往的日志全部转成一个漂亮的CHM。它的搜索体验我觉得比Evernote更好，全文检索的index使得搜索特别快。再多的就不介绍了，敢兴趣的可以自行了解。
