DEVTIPS #7 JSON Message

Class defenitions for serialization:

[Serializable]

public class JsonQuery

{

    public string licenseKey;

    public string layoutName;

    public List<JsonQueryItem> items;

}

[Serializable]

public class JsonQueryItem

{

    public string fieldRef;

    public string comparison;

    public string value;

}

Javascript JSON Message:

   var query = {

                licenseKey: "3c67897",

                layoutName: "hemma",

                items: [

                    {

                        fieldRef: "PRODUCT_CODE",

                        comparison: "Contains",

                        value: "hepa"

                    }

                ]

            };

DEVTIPS #6 JSON Serialization with .NET

.NET 3.5 Has JSON serialization built-in.

Include these references:

using System.Runtime.Serialization.Json;

using System.Runtime.Serialization;

Make a serializable object defenition (class):

[Serializable]

public class JsonQuery

{

    public string licenseKey;

    public string layoutName;

    public List items;

}

Make two generic functions for serialize and deserialize JSON Message:

    private object JsonDeserialize(string json, Type type)

    {

        MemoryStream ms = new MemoryStream(Encoding.Unicode.GetBytes(json));

        DataContractJsonSerializer dcjs = new DataContractJsonSerializer(type);

        object o = dcjs.ReadObject(ms);

        ms.Close();

        return o;

    }

    private string JsonSerialize(object obj, Type type, string callback)

    {

        DataContractJsonSerializer ser = new DataContractJsonSerializer(type);

        MemoryStream ms = new MemoryStream();

        ser.WriteObject(ms, obj);

        string json = Encoding.Default.GetString(ms.ToArray());

        ms.Close();

        return callback + "(" + json + ")";

    }
