How do I pass list of objects and string back to server?

Please look at the my code. It tried to debug, it never get back to server. it throws error :
Possibly unhandled rejection: obj' is not supported for deserialization of an array

What I have tried:

<tr ng-repeat="r in Students">
<pre><asp:TextBox ID="fnBox" runat="server" class="form-control" placeholder="file name" ng-model="xlfileName"></asp:TextBox>

<input type="button" value="SendFile" ng-click="SendFile(Students)" />


$scope.SendFile = function (Data) {

      var dataArray = [];

            method: "POST",
            url: "StudentList.aspx/GetStudent",
            data: { dataList:dataArray},
            contentType: "application/json",
            dataType: "json"
        }).then(function (response) {



public static string GetStudent(List<DemoList> dataList)


public class DemoList
       public List<Student> students { get; set; }
       public string Fn { get; set; }

since my requirement needed to pass the fileName also along with list of students now it created another problem.
