Hi Sonali,
You can achive as below way but you need to check when you pass int array to querystring because it has some limits to number of querystring length.

Page from you are passing Querystring,
var array = new int[] { 10, 20, 30, 40 };
               string ids = string.Join(",", array);
               Response.Redirect("Default.aspx?ids=" + ids);
Once you redirect, You need to get querstring in redirected page,
First need to check querystring for null check, if not null then get values from querystring as below,
if (Request.QueryString["ids"] != null)
{
var ids = Request.QueryString["ids"].ToString().Split(',').Select(int.Parse).ToArray();
}

there are multiple options
the easiest one is as follow
int [] arr={1,2,3,4,5}
var query = "";
        for (var i = 0; i < arr.length; ++i) {
            query += arr[i] + ",";
        }

Response.Redirect("home.aspx?Numbers="+query);
now you can retrieve it as
int[] ids = Request.QueryString["Numbers"]
.Split( new[] {","}, StringSplitOptions.RemoveEmptyEntries );
