Error trying to access a collection

[Michael Hawksworth]

Hi folks

I am trying to use the following to read all the records from the admin database collection and drop them into a list(or something but that's not material)...

            using (var database = new MongoAdmin(mongoConnectionString))

            {

                var db = database.Database;

                var collection = db.GetCollection(theSelectedCollection);

                var numberOfRecords = collection.Count();

                var records = collection.Find();

                // display records in list...

            }

however it throws the following exception in the deserialiser.ReadObject(Type type) routine

Deserialization failed: type System.Object does not have a property named xxx

I've tried to dig through it and it is returning null from FindProperty() in the TypeHelper which causes it to then throw an error.

I have also tried using a query provider but get the same exception.

            using (var qp = MongoQueryProvider.Create(mongoConnectionString))

            {

                var selectedCollection = (string)this.listCollections.SelectedItems[0];

                var collection = qp.DB.GetCollection(theSelectedCollection);

                ...

Is it because I am using GetCollection() and not GetCollection<>()?

And if so what should the entry be for T when we are looking at admin collections and what GetCollection() is for?

Cheers.

Ok scratch some of that! Loosing the plot trying to do too many things
at once :( before I go on holiday :)

Simply I am trying to get all the records from a collection when I
don't know the structure, it's for a simple mongodb viewer I am
knocking together.

Any suggestions would be appreciated.

Michael.

just do "GetCollection<Expando>("collectionName") and you'll get back "stuff"

I spoke too soon, this is an issue that another contributor brought
up, I am going to see what I can do to fix it and will post back to
the group when I have something.

Micheal,

If you pull the latest from my repo, your code should work. Let us know what you find.

Thanks Andrew.

I'll have to have a look when I get back from Holiday (Wife seems to think I shouldn't take my laptop for some reason, odd I know!)

Great work by the way. Mongo is a learning curve but with NoRM and this group it is fun.  I'm really impressed with the commitment you guys have given to this.

your wife is right, don't take your laptop on vacation (I should learn this lesson!)

and thanks, it really has been awesome to get so much help on the project, I think users keep us motivated. :-)
