How to load Arraylist

Question

Here I load array from data table to array list

public static ArrayList LoadView()
{
DataTable dt = new DataTable();
DataView view = new DataView(dt);
view.RowFilter = (("Name='AD'"));
DataTable dtcopy = view.ToTable("Selected", false, "Row1", "Row2");
var arr = dtcopy.Rows.Cast<DataRow>().Select(r => r.ItemArray).ToArray();
ItemList.Add(arr1);

DataView view2 = new DataView(dt);
view2.RowFilter = (("Name='ProE'"));
DataTable dtcopy2 = view2.ToTable("Selected", false, "Row1", "Row2");
// remove some column from datatable
var arr2 = dtcopy2.Rows.Cast<DataRow>().Select(r => r.ItemArray).ToArray();//Convert datatable to array
//return arr2;
ItemList.Add(arr2);

return Itemlist;
}

Here i have two arrays in my array list.Now i want to append it in a particular array in javascript

 

Javascript:
PageMethods.LoadView();
function LoadSucc(obj,obj1)//Retur arraylist
{
var goog = [];
goog = obj;

var goog1 = [];
goog1 = obj1;
 }

Hope you undestand my problem .Suggest me some ideas to solve my issue
