how to retrieve an array passed in url in controller asp.net MVC2 application

[youpi sarah]

I trying to develop an application asp.net MVC2, I need to retrieve an array of integers already spent in url in my controller. I recovered in a string but I need the recovered in its original form, but I do not know how to do that?
Here is my javascript code

 var Elmt = document.getElementById('MyTable');
            var elmt = Elmt.getElementsByTagName('input');
            var lgth = elmt.length;
            var lst = new Array();
            var k=0;
            for (var i = 0; i < lgth; i++) {
                if ((elmt[i].type == 'checkbox') && (elmt[i].checked == true)) {
                    lst[k] = elmt[i].value;
                    k++;
                }
            }
            
             document.location.href = "DeleteSelectedMsg?ListeId="+lst;

in the controller

 string x = Convert.ToString(Request["ListeId"]);
