[OperationContract]
    public FareDataModel GetFareAndDistanceJson(string source, string destination, string country, string city)
    {
       return  FareManager.GetFare(source, destination, country, city);


    }

svc クラスに上記のメソッドがありますが、Json でデータを完全に送信することはできません。以下の結果が得られます

 {
"d": {
    "__type": "FareDataModel:#MeterupAutoTaxiWebService",
    "Fares": [
        {
            "__type": "VehicleFare:#MeterupAutoTaxiWebService"
        }
    ]
}
}

しかし、文字列として返すと、データを取得しますが、文字列の形式で取得します。本当にjsonを取得したいです。ここに私の FareDataModel オブジェクトがあります

 [DataContract]
    public class FareDataModel
    {
        public string SourceAddress;
        public string DestinationAddress;
        public int Duration;
        public int Distance;
        public string Error;

        [DataMember]
        public List<VehicleFare> Fares = new List<VehicleFare>();
    }


    [DataContract]
    public class VehicleFare
    {
        public string PhoneNo;
        public string Vehicle;
        public double Fare;
    }

投稿の1つで説明されているすべての変更を試しましたが、何も機能していません. 以下のようにコードを変更して文字列として返すと

[OperationContract]
    public string GetFareAndDistanceJson(string source, string destination, string country, string city)
    {

       return new JavaScriptSerializer().Serialize(FareManager.GetFare(source, destination, country, city));

    }

次の結果が得られます

    {
    "d": "{\"SourceAddress\":\"Majestic, Bangalore, Karnataka, India\",\"DestinationAddress\":\"Marathahalli Market, Bangalore, Karnataka, India\",\"Duration\":2475,\"Distance\":19872,\"Error\":null,\"Fares\":[{\"PhoneNo\":null,\"Vehicle\":\"Auto\",\"Fare\":238}]}"
}

真のjson応答が本当に必要です。

これが私のクラスです

[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class Service1
{



    [OperationContract]
    public string GetFareAndDistanceJson(string source, string destination, string country, string city)
    {

       return new JavaScriptSerializer().Serialize(FareManager.GetFare(source, destination, country, city));

    }
    // Add more operations here and mark them with [OperationContract]
}

私を助けてください。
