Deserialize JSON output

[anguoyang]

Hi, all,
I am using C# to deserialize the json output from dede server, but always return "null", I defined the Json object as follow:

    [DataContract]
    [Serializable]
    public class head
    {
        [DataMember]
        public string method { get; set; }
        [DataMember]
        public int time { get; set; }
        [DataMember]
        public string service { get; set; }

    }

    [DataContract]
    [Serializable]
    public class status
    {
        public status() 
        {
            this.code = 0;
            this.msg = "";
        }
        [DataMember]
        public int code { get; set; }
        [DataMember]
        public string msg { get; set; }

    }

    [DataContract]
    [Serializable]
    public class probs
    {
        public probs() 
        {
            this.prob = 0.0;
            this.cat = "";
        }
        [DataMember]
        public double prob { get; set; }
        [DataMember]
        public string cat { get; set; }

    }

    [DataContract]
    [Serializable]
    public class classes
    {
        [DataMember]
        public probs[] _probs { get; set; }

    }

    [DataContract]
    [Serializable]
    public class predictions
    {
        public predictions() 
        {
            this._classes = new classes();
            this.uri = "";
            this.loss = 0;
        }

        [DataMember]
        public string uri { get; set; }
        [DataMember]
        public int loss { get; set; }
        [DataMember]
        public classes _classes { get; set; }
    }

    [DataContract]
    [Serializable]
    public class body
    {
        public body() 
        {
            this._predictions = new predictions();
        }
        [DataMember]
        public predictions _predictions { get; set; }

    }

    [DataContract]
    [Serializable]
    public class JSonPredictData
    {
        public JSonPredictData() 
        {
            this._status = new status();
            this._head = new head();
            this._body = new body();
        }

        [DataMember]
        public body _body { get; set; }

        [DataMember]
        public head _head { get; set; }

        [DataMember]
        public status _status { get; set; }

    }

and using NewtonSoft to deserialize it:
JSonPredictData result = (JSonPredictData)JsonConvert.DeserializeObject(JsonString, typeof(JSonPredictData));

Here, the JsonSting is:

{"status":{"code":200,"msg":"OK"},"head":{"method":"/predict","time":33061.0,"se
rvice":"imageserv"},"body":{"predictions":{"uri":"http://www.deepdetect.com/img/
ambulance.jpg","classes":[{"prob":0.9928520321846008,"cat":"n02701002 ambulance"
},{"prob":0.0069321757182478909,"cat":"n03977966 police van, police wagon, paddy
wagon, patrol wagon, wagon, black Maria"},{"last":true,"prob":0.000069531641202
04747,"cat":"n03769881 minibus"}]}}}

What is wrong with my class definition? thanks.

JSonPredictData result = (JSonPredictData)JsonConvert.DeserializeObject(JsonString, typeof(JSonPredictData));

The result always return null.

If I understand correctly, dd works fine, and there's an issue with your client code ? If so, you may get more attention on a .Net forum or on stackoverflow...
There's no C# official dd client on the roadmap yet, but if you decide that you would like to take the opportunity to write and share one, we'll help as possible.

[anguoyang]

hi,@beniz,I would like to share the code, pull request it in about 2days

[beniz]

hi @anguoyang any difficulties with a C# client ? Just wondering if I should rename / refocus this ticket on a C# client to the dd API ?

[anguoyang]

hi @beniz , Sorry for the late, I have just commit the source code and send the pull request, please check it, thanks a lot.

[beniz]

hi @anguoyang thanks, I guess this is the code here: anguoyang@3839d39

You'd need to PR it to fit into the dd repository, or maybe easier, to make an external repository of it (e.g. deepdetect-csharp-client) and then we can review it together, test it etc...

As a first remark, your code appears to include possible binary files such as csharpClient.exe which should probably not be there.

[anguoyang]

HI, @beniz , I have deleted the binary files and PR it into ./clients/csharp.
https://github.com/beniz/deepdetect/pull/98
Please check it, please let me know if there are still problems. Thanks.
