Error in SearchVenues

[michaelpimentel]

Today my application started showing error 410 message in the search operation. I did a little debugging and find it would be something new requirement of the foursquare api related to parameter "V" . So resolve to upgrade SharpSquare to the latest version that is here in github, however I am having the error below:

Msg:
Cannot deserialize the current JSON array (e.g. [1,2,3]) into type 'FourSquare.SharpSquare.Entities.FourSquareEntityItems`1[FourSquare.SharpSquare.Entities.Venue]' because the type requires a JSON object (e.g. {"name":"value"}) to deserialize correctly.

To fix this error either change the JSON to a JSON object (e.g. {"name":"value"}) or change the deserialized type to an array or a type that implements a collection interface (e.g. ICollection, IList) like List that can be deserialized from a JSON array. JsonArrayAttribute can also be added to the type to force it to deserialize from a JSON array.

Path 'response.neighborhoods', line 1, position 50.

Here:
public List SearchVenues(Dictionary<string, string> parameters)
{
FourSquareEntityItems venues = GetSingle<FourSquareEntityItems>("/venues/search", parameters, true).response["groups"];

        return venues.items;
    }

I bet this is the "icon" parameter being improperly defined, same as in the bug I reported a short while ago.

I have made a blog post about it
http://msprogrammer.serviciipeweb.ro/2014/02/09/solving-no-parameterless-constructor-defined-for-type-of-system-string/
could you add the code and see what it is missing?

The SharpSquare code was updated on 5 February to solve the icon issue. Grab a new copy of it and you should be all set. It solved my issue.

I have forked again. My problem was in check list

Are you trying to use the SearchVenues method?

[ccsimpson3]

any way, to work around this I changed the SearchVenues method to use "GetMultiple" e.g.

 public List<Venue> SearchVenues(Dictionary<string, string> parameters)
    {
        return GetMultiple<Venue>("/venues/search", parameters, true).response["venues"];
    }

and then added this bit to the utilized "GetMultiple" method

int index = json.IndexOf(","confident");
if (index > 0)
json = json.Substring(0, index);
json = json + "}}";

directly after:

string json = Request(string.Format("{0}{1}?{2}{3}&v={4}", apiUrl, endpoint, oauthToken, serializedParameters,apiVersion), HttpMethod.GET);

I'm almost certain this will cause problems later on but it works for what I need so I thought I'd share

[aledut]

For me just by switching the GetSingle to GetMultiple already worked.

thanks a lot man!

[ccsimpson3]

great! no problem

[ignatandrei]

Please add this code
var obj = new JavaScriptSerializer().Deserialize<Dictionary<string, object>>(json); //json parameter is the string content of the api
= DeserializeObject(obj, typeof()) as ;

( see my post)
to see what is wrong.

[ccsimpson3]

following the instructions in the post I received:

An exception of type 'Microsoft.CSharp.RuntimeBinder.RuntimeBinderException' occurred in System.Core.dll but was not handled in user code

Additional information: 'FourSquare.SharpSquare.Entities.FourSquareEntityItems<FourSquare.SharpSquare.Entities.Venue>' does not contain a definition for 'Add'

[ignatandrei]

Could you share a sample project?

[ignatandrei]

I need the json returned and the call in 4sq ...

[ccsimpson3]

it's an unmodified version of SharpSquare.cs that I applied the revisions too
