Json.NET将类列表作为属性

Question

I build a rest service which output are json. I using Newtonsoft.Json.

This is my class.

public class DownloadPDA
{
    public List<FRUTE> lsRute { get; set; }
    public List<FCUSTMST> lsCustomer { get; set; }
    public List<FMASTER> lsMaster { get; set; }
    public List<FNOTEC> lsNotec { get; set; }
    public List<FINFO> lsInfo { get; set; }
    public List<FBRAND> lsBrand { get; set; }
    public List<FKPL> lsKpl { get; set; }
}

but when I test my rest service my result are:

{"downloadDataResult":"{"lsBrand":[{}],"lsCustomer":[{},{},{}],"lsInfo":[],"lsKpl":null,"lsMaster":[{},{},{},{},{}],"lsNotec":[],"lsRute":[{},{},{}]}"}

it not show the data in list. I know something is wrong. Can anybody help?

This one of my collection class

public class FRUTE
{
    private String norute;
    private String custno;
    private String flag;
    private String st_visit;
    private float amount;
    private int jmlvisit;

    public FRUTE() { }

    public void getData(DCTRTDTO dto) {
        this.norute = dto.NOROUT;
        this.custno = dto.NOCUST;
        this.flag = dto.FLAG;
        this.st_visit = "not yet";
        this.amount = 10;
        this.jmlvisit = 1;
    }

    public static List<FRUTE> getList(List<DCTRTDTO> lsRute)
    {
        List<FRUTE> ls = new List<FRUTE>();
        FRUTE info = new FRUTE();

        foreach (DCTRTDTO dto in lsRute)
        {
            info.getData(dto);
            ls.Add(info);
        }

        return ls;
    }
}

Your FRUTE class doesn't have public properties that are required for Json serialization. Encapsulate you private fields and all will work as expected.

public class FRUTE
{
    private String norute;
    private String custno;

    public string Norute
    {
        get { return norute; }
        set { norute = value; }
    }

    public string Custno
    {
        get { return custno; }
        set { custno = value; }
    }
    //...
}
