Deserialize array of key value pairs using Json.NET

by

The simplest way is deserialize array of key-value pairs to IDictionary<string, string>:


public class SomeData
{
    public string Id { get; set; }

    public IEnumerable<IDictionary<string, string>> Data { get; set; }
}

private static void Main(string[] args)
{
    var json = "{ \"id\": \"123\", \"data\": [ { \"key1\": \"val1\" }, { \"key2\" : \"val2\" } ] }";

    var obj = JsonConvert.DeserializeObject<SomeData>(json);
}

But if you need deserialize that to your own class, it can be looks like that:


public class SomeData2
{
    public string Id { get; set; }

    public List<SomeDataPair> Data { get; set; }
}

public class SomeDataPair
{
    public string Key { get; set; }

    public string Value { get; set; }
}

private static void Main(string[] args)
{
    var json = "{ \"id\": \"123\", \"data\": [ { \"key1\": \"val1\" }, { \"key2\" : \"val2\" } ] }";

    var rawObj = JObject.Parse(json);

    var obj2 = new SomeData2
    {
        Id = (string)rawObj["id"],
        Data = new List<SomeDataPair>()
    };

    foreach (var item in rawObj["data"])
    {
        foreach (var prop in item)
        {
            var property = prop as JProperty;

            if (property != null)
            {
                obj2.Data.Add(new SomeDataPair() { Key = property.Name, Value = property.Value.ToString() });
            }

        }
    }
}

See that I khow that Value is string and i call ToString() method, there can be another complex class.
