Question

我在angularjs中使用asp.net web API，我正在调用返回数据表的Web API方法，但是有两倍的项目;例如如果datatable有2行，则响应有4行。

在该示例中，该方法应仅返回2行，但在客户端，它显示所有项目都在数组中重复。

如何在不获取重复数据的情况下正确检索它？

返回2行的Webmethod

//// GET api /

public HttpResponseMessage Get()
{            
long id = 791;
DateTime dFromDate = DateTime.MinValue;
DateTime dToDate = DateTime.MinValue;

DataSet ds_jobs = DAL.Jobs.FilterJobByRecruiterId_new("", dFromDate, dToDate, "all", id, 1, 2, true, 2);

if (ds_jobs == null || ds_jobs.Tables.Count == 0 || ds_jobs.Tables[0].Rows.Count == 0)
            throw new HttpResponseException(HttpStatusCode.NotFound);

return Request.CreateResponse<IEnumerable<DataRow>>(HttpStatusCode.OK, ds_jobs.Tables[0].AsEnumerable());  
}

使用上述方法的AngularJS代码

   var recruiter = angular.module('recruiter', []);

    recruiter.service('jobsService', ['$http', function ($http) {


    this.getAllJobsByRecruiterId = function () {
    $http.get('http://localhost:51315/api/recruiter').success(function (result) {
    return result[0].Table;
    });
    };

    } ]);



recruiter.controller('jobsController', ['$scope', 'jobsService', function ($scope,     jobsService) {


var recId = 791;

$scope.Jobs = jobsService.getAllJobsByRecruiterId();

} ]);

响应窗口（在浏览器中）有以下o / p

============= 请参见结果集中每次重复2次的作业ID 283499,283498，即使数据表仅有2行。奇怪的行为！

将数据表转换为JSON会导致重复数据
