博客的分类比较混乱，那是随笔又比较多，一个个去修改很麻烦，所以参考网上写了个程序，用以批量修改博客。
代码还有以下问题，当获取单个Post，因服务器返回的postid被影射为int64类型，而实际接口应该是string类型。因此会报转换错误，目前还没有想到好的解决方法。
首先需要引用CookComputing.XmlRpc，项目属性---应用程序---目标框架选.Net Framework 4 而非 Client Profile
代码如下：
1. 新建windows窗体程序。
2. 新建Structs.cs文件，代码如下：

3. 编辑Form.cs，添加两个ListBox，分部命名为cats和posts，用来展示所有分类和所有随笔，同时都设置为可多选。添加3个button，分部是fresh、apply、add，以及一个文本输入框TextBox。add用来添加文本框内的分类，fresh用来删除已经有分类的随笔，apply用来应用随笔分类。
