用于WCF REST服务的JSON.NET Serializer

我试图使用 NETFx Json.NET MediaTypeFormatter nuget包在我的WCF REST服务(4.0框架)中交换默认的DataContractJsonSerializer.我在我的项目中下载了包,并在Global.asax文件中添加了以下代码行.

void Application_Start(object sender,EventArgs e)
    {
        RegisterRoutes();

        // Create Json.Net formatter serializing DateTime using the ISO 8601 format
        var serializerSettings = new JsonSerializerSettings();
        serializerSettings.Converters.Add(new IsoDateTimeConverter());

        var config = HttpHostConfiguration.Create();
        config.Configuration.OperationHandlerFactory.Formatters.Clear();
        config.Configuration.OperationHandlerFactory.Formatters.Insert(0,new JsonNetMediaTypeFormatter(serializerSettings));
    }

但是当我运行该服务时,它仍然使用DataContractJsonSerilizer进行序列化.以下是我从我的服务中返回的课程.

[DataContract]
public class SampleItem
{
    [DataMember]
    public int Id { get; set; }

    [DataMember]
    public string StringValue { get; set; }

    [DataMember]
    public DateTime DateTime { get; set; }
}

以下是fiddler服务的回复.

您可以看到DateTime不是我在上面代码中的serializerSettings中指定的ISO格式.这告诉我JSON.NET序列化程序不用于序列化对象.

非常感谢任何帮助.

我找到答案后感到愚蠢.有时发生:).我不得不将配置添加到RouteTable.下面是Global.asax中的代码

public class Global : HttpApplication
{
    void Application_Start(object sender,EventArgs e)
    {
        RegisterRoutes();
    }

    private void RegisterRoutes()
    {
        // Create Json.Net formatter serializing DateTime using the ISO 8601 format
        var serializerSettings = new JsonSerializerSettings();
        serializerSettings.Converters.Add(new IsoDateTimeConverter());

        var config = HttpHostConfiguration.Create().Configuration;
        config.OperationHandlerFactory.Formatters.Clear();
        config.OperationHandlerFactory.Formatters.Insert(0,new JsonNetMediaTypeFormatter(serializerSettings));

        var httpServiceFactory = new HttpServiceHostFactory
                                     {
                                         OperationHandlerFactory = config.OperationHandlerFactory,MessageHandlerFactory = config.MessageHandlerFactory
                                     };

        RouteTable.Routes.Add(new ServiceRoute("Service1",httpServiceFactory,typeof(Service1)));
    }
}

希望它能帮助某人,如果他们碰巧遇到同样的情况.
