WordPress 2.5 XML-RPC wrapper for .Net

Note: there is a newer version available here.

While upgrading and consolidating some older stuff to WP 2.5.1 I needed a .Net wrapper to the metaWebLog API of WordPress. The XML-RPC.Net library helps you a long way in achieving this but the last bits are somewhat tricky and each new version of WP is altering things. So, I cooked some code together which you can find below.

The API is self-descriptive but the novel thing is the possibility to upload media straight to your blog, like the following:

WP.Publisher api = new WP.Publisher("admin", "Unknown");
WP.MediaObject media = new WP25API.MediaObject();
media.type = "jpg";
media.name = "test.jpg";
 
media.bits = WP.Publisher.ConvertImageToByteArray(new Bitmap(@"C:\temp\SomeImage.jpg"), 
    System.Drawing.Imaging.ImageFormat.Jpeg);
 
WP.MediaObjectInfo info= api.AddMedia(media);

Easy. Would in fact allow one to use the blog as a file repository (I noticed my host moved the max to 380GB recently).
