Question

我创建了一个WCF服务来返回JSON，但是，它不会以我需要的方式返回。

我的界面：

[ServiceContract]
public interface IService1
{
    [OperationContract(Name="Sensors")]
    [WebInvoke(
        Method = "GET",
        ResponseFormat = WebMessageFormat.Json,
        BodyStyle = WebMessageBodyStyle.Bare,
        UriTemplate = "test")]
    List<Sensor> testdata();
}

我的服务：

public class Service1 : IService1
{
    public List<Sensor> testdata()
    {
        return HamsData.GetSensorDetails("1");
    }
}

HamsData.GetSensorDetails：

    public static List<Sensor> GetSensorDetails(string id)
    { 
        List<Sensor> al = new List<Sensor>();
        DateTime now = DateTime.Now;
        DateTime thishour = new DateTime(now.Year, now.Month, now.Day, now.Hour, 0, 0);
        using ( HAMSDataClassesDataContext db = new HAMSDataClassesDataContext())
        {
            var dbsensors = (from p in db.sensordetails where p.sensorlatestdate == thishour select new Sensor { name = p.sensor.name, value = p.sensorlatestvalue });
            foreach (Sensor x in dbsensors)
            {
              al.Add(x);
            }
            return al;
        }
    }

传感器类：

[Serializable]
[DataContract(Name = "mysensor")]
public class Sensor
{
    [DataMember]
    public string name { get; set; }

    [DataMember]
    public decimal value { get; set; }
}

返回以下JSON：

[{"name":"EIC","value":1000.000},{"name":"GIC","value":0.000},{"name":"WIC","value":0.000},{"name":"EHC","value":0.010},{"name":"GHC","value":0.000},{"name":"WHC","value":0.000},{"name":"EDC","value":33458.560},{"name":"ENC","value":27450.040},{"name":"GRC","value":35227.100},{"name":"WRC","value":38.390},{"name":"ECR","value":1.000},{"name":"10:D8:A2:DC:01:08:00:E0:T","value":24.120},{"name":"10:94:3D:B4:01:08:00:BC:T","value":46.310},{"name":"10:31:85:70:01:08:00:4D:T","value":20.940},{"name":"10:5D:5E:B4:01:08:00:EA:T","value":7.690},{"name":"10:DD:56:B4:01:08:00:3E:T","value":17.690},{"name":"28:51:32:5D:02:00:00:0A:T","value":12.560},{"name":"26:B1:08:81:00:00:00:39:T","value":15.030},{"name":"26:B1:08:81:00:00:00:39:H","value":-29.890},{"name":"26:CD:A0:6D:00:00:00:8A:T","value":15.030},{"name":"26:CD:A0:6D:00:00:00:8A:L","value":204.600}]

但是，我希望它没有名称和值标签，如：

[{"EIC":1000.000},{"GIC":0.000},{"WIC":0.000},{"EHC":0.010},{"GHC":0.000},{"WHC":0.000},{"EDC":33458.560},{"ENC":27450.040},{"GRC":35227.100},{"WRC":38.390},{"ECR":1.000},{"10:D8:A2:DC:01:08:00:E0:T":24.120},{"10:94:3D:B4:01:08:00:BC:T":46.310},{"10:31:85:70:01:08:00:4D:T",e":20.940},{"10:5D:5E:B4:01:08:00:EA:T":7.690},{"10:DD:56:B4:01:08:00:3E:T":17.690},{"28:51:32:5D:02:00:00:0A:T"12.560},{"26:B1:08:81:00:00:00:39:T":15.030},{"26:B1:08:81:00:00:00:39:H":-29.890},{"26:CD:A0:6D:00:00:00:8A:T":15.030},{"26:CD:A0:6D:00:00:00:8A:L":204.600}]

有人能说出我在这里做错了吗？

这不是json，这就是问题所在。 Json编码是属性/值的组合。你试图滥用它。

您确定要以这种方式对数据进行编码吗？这使得提取值变得非常困难。

没有名称/值的WCF Json结果
