将对象数组发送到WCF [英] Sending array of objects to WCF

问题描述

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.我尝试了以下代码，但它 无法正常工作.

In my application i want to save the data by using jQuery and Ajax.I have a WCF Service. I want to save a List of Objects by using ajax.I have tried with following code, but it is not working.

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，我试图发送列表数据.但是内部服务器错误来了.我没有到达实际上我错的地方，还有其他方法可以将对象列表发送到WCF吗?

In this way i am trying to send the list data.But internal server error is coming.I am not getting where actually i am wrong.Is there any other way to send the list of objects to WCF ?

谢谢

推荐答案

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; }
}

我所缺少的是

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

第二点myEntity键应该在最终的json对象中. 与wcf方法对象参数相同.

The 2nd point myEntity key should be there in the final json object.And the key should be same as the wcf method object parameter.

谢谢
