Object cannot be stored in an array of this type.
This was the error that was biting me on PostXING v2 for almost a week (I usually only get insomnia hours to debug. That can be frustrating.)
The first thing that I noticed was that the wonderful interfaces that I was using would end up null after my first visit to a particular configuration page. It’s something about the way that a “Page” is saved and loaded - it requires ViewState! Forreal! I’d gotten so used to having state within my smart clients that I had almost forgot about reconstructing state.
Now that I had that taken care of, I was getting an exception returned from what seemed to be the service endpoint of the metablog api. But wait a second - I’m using nearly the same code in v1. So I think, hey, I’ll go ahead and use exactly the same code from v1 and put that in there - that’ll surely work, right?
using System; using CookComputing.XmlRpc; namespace PostXING.MetaBlogProvider { /// <summary> /// BlogRequest wraps the blogger api getUsersBlog xml-rpc method. /// </summary> public class BlogRequest : XmlRpcClientProtocol { public BlogRequest(){ } [XmlRpcMethod("blogger.getUsersBlogs", Description="Returns information on all the blogs a given user " + "is a member.")] public bgBlogInfo[] getUsersBlogs(string appKey,string username,string password) { return (bgBlogInfo[])Invoke("getUsersBlogs",new object[]{appKey,username,password}); } } }
Nope, same exception (the title of this post). After the dent in my head grew to about three inches, I decided to look at the version of xml-rpc.net that I was using. Hmm, 0.8. What version was the endpoint using? Double hmm, 0.9. Could it be a simple version mismatch that was my problem giving me this cryptic error?
Yep.</span>
