C# How can i deserialize json DATAS array in the simple struct?

Question

{
    "ASD": { "CONNECTIONS": 1, "DATAS": [0, 0, 0] },
    "Something": {
        "PITCH": 77,
    }
}    

data = JsonConvert.DeserializeObject<DATA>(text);

public class DATA
{
    public struct ASD
    {
            public float CONNECTIONS;
            public float[] DATAS; //?? This is every time is null
    }

    public struct Something
    {
        public float PITCH;
   }
}

Could you add the code and the models that you are using to deserialize the JSON. Please add them as text to the question rather than images. — phuzi

It is not enough to simply define the structs you want to use. The object ASD must have properties typed as these structs. (Note the 0 references hint above the definitions in your screenshot!)

public class DATA
{
    public ASD ASD{get;set;}
    public Something Something {get;set;}
}

public struct ASD
{
    public float CONNECTIONS;
    public float[] DATAS; //?? This is every time is null (not any more it wont be!)
}

public struct Something
{
    public float PITCH;
}

Yes, I did this, but the DATAS array in the ASD struct is null, i tried to write out the message in the console and the DATAS wasn't zero"ASD":{"CONNECTIONS":1,"DATAS":[4,23,1]}.

@Smeth Seems to work fine for me - look here: dotnetfiddle.net/MByBMP You must be doing something else wrong

Maybe, actually everything else working fine only the Datas array return null. I will try to figure it out...
