Cannot deserialize the current JSON array

[semihmasat]

Hello,

I am new arround here and i tried using SharpSquare. I tried to build a simple app by i am getting this result. ( at the end of the post )

Can you guys help me out ?

Do i need token or something ? How do i do that ?

SharpSquare sharpSquare = new SharpSquare("Client id", "Client secret");

Dictionary<string, string> parameters = new Dictionary<string, string>();
parameters.Add("ll", "51.508515,-0.1254872");
parameters.Add("categoryId", "4d4b7105d754a06374d81259"); //Food
parameters.Add("radius", "5000");
parameters.Add("limit", "50");
var result = sharpSquare.SearchVenues(parameters);

result.Wait();

ERROR 👍

•   Thrown: "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.

In my case it has to do something with 'what' parameter from 'geocode'. Here's the path from exception:
Path 'response.geocode.what', line 1, position 5573.

I've fixed the issue by implementing a new class that is suitable only for getting venues, the class looks like this:

public class FourSquareMultipleVenuesResponse<T> : FourSquareResponse where T : FourSquareEntity
    {
        public VenueResponse<T> response
        {
            get;
            set;
        }
    }

    public class VenueResponse<T>
    {
        public Dictionary<string, object> geocoded
        {
            get;
            set;
        }
        public List<T> venues
        {
            get;
            set;
        }
    }

I've implemented new method GetMultipleVenues<T> which utilizes this class (based on existing GetMultiple method. It's a hack but it's working :)

I have same issue here..
Is there any tutorial for search venues?

EDIT:
Yesterday I'm using Sharpsquare from nuget. Now I'm using Sharpsquare from github and it's working. Seems like SharpSquare in nuget isn't updated.

Yes, Github version it`s working but Nuget version had same issue.

I had the same issue with the SharpSquare Nuget package.
I uninstalled it and I downloaded the SharpSquare library from https://github.com/TICLAB/SharpSquare. I opened the project in Visual Studio. It could not find Newtonsoft even though it was installed, so I uninstalled Newtonsoft and installed it again via the Nuget package manager. I then referenced the SharpSquare library in my code and it worked.
