使用'Link'标头对Shopify API请求进行分页

Question

如何遍历每个请求的标头，而不只是httpResponse标头？

   var httpWebRequest = (HttpWebRequest)WebRequest.Create("https://" + encodedUser + ":" + encodedPass + "@xxxx.com/admin/api/2019-10/orders.json?fields=name,created_at,shipping_address");

string next_results_page = "";
                for (int i = 0; i < httpResponse.Headers.Count; i++)
                {
                    var headerKeys = httpResponse.Headers.Keys[i];

                    //Console.WriteLine("\nHeader Name: {0}, Value: {1}", httpResponse.Headers.Keys[i], httpResponse.Headers[i]);
                    if (httpResponse.Headers.Keys[i].Equals("Link"))
                    {
                        Console.WriteLine(httpResponse.Headers[i]);
                        next_results_page = httpResponse.Headers[i].Replace("<", "").Replace(">", "").Insert(8, "APIUSER" + ":" + "APIPASS@");
                    }
                }
var nextPageReq = (HttpWebRequest)WebRequest.Create(next_results_page);
