jquery - 将对象数组发送到 WCF

Question

在我的应用程序中，我想使用 jQuery 和 Ajax 保存数据。我有一个 WCF 服务。我想使用 ajax 保存对象列表。我尝试过以下代码，但它不工作。

jquery 代码:

      var listOfObjects=new Array();

      //creating list of objects
      for(var i=0;i<5;i++)
       {   var MyEntity=new Object();
           MyEntity.TestId =i;
           MyEntity.TestId =i+"testName";
           listOfObjects.push(MyEntity);
       }

        //Saving info
        $.ajax({
            type: "POST",
            async: false,
            data: JSON.stringify(listOfObjects),
            url: "../ServiceLayer/myService.svc/SaveResults",
            contentType: "application/json; charset=utf-8",
            dataType: "json",          
            success: function () {
                alert("success");
            },
            error: function () {
                alert("Error");
            }
        });

WCF:

    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json,
     ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public void SaveLabResults(List<MyEntity> myEntity)
    {
          var lstEntities=myEntity;
    }

实体:

[DataContract]
public class MyEntity
{
    [DataMember]
    public string TestId { get; set; }
    [DataMember]
    public string TestName { get; set; }
}

通过这种方式，我尝试发送列表数据。但是内部服务器错误即将到来。我没有得到实际上我错的地方。是否有其他方法将对象列表发送到 WCF ？

谢谢

jquery 代码:

      var listOfObjects=new Array();

      //creating list of objects
      for(var i=0;i<5;i++)
       {   var MyEntity=new Object();
           MyEntity.TestId =i;
           MyEntity.TestId =i+"testName";
           listOfObjects.push(MyEntity);
       }

       var jsonList=JSON.stringify(listOfObjects);
       var dataToSend = '{"myEntity":'+jsonList+'';

        //Saving info
        $.ajax({
            type: "POST",
            async: false,
            data: dataToSend,
            url: "../ServiceLayer/myService.svc/SaveResults",
            contentType: "application/json; charset=utf-8",
            dataType: "json",          
            success: function () {
                alert("success");
            },
            error: function () {
                alert("Error");
            }
        });

WCF:

    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Json,
     ResponseFormat = WebMessageFormat.Json, BodyStyle = WebMessageBodyStyle.WrappedRequest)]
    public void SaveLabResults(List<MyEntity> myEntity)
    {
          var lstEntities=myEntity;
    }

实体:

[DataContract]
public class MyEntity
{
    [DataMember]
    public string TestId { get; set; }
    [DataMember]
    public string TestName { get; set; }
}

我缺少的是

 1.var jsonList=JSON.stringify(listOfObjects);
 2.var dataToSend = '{"myEntity":'+jsonData+''; 

第二点 myEntity 键应该存在于最终的 json 对象中。并且该键应该与wcf方法对象参数相同。

谢谢
