C# 如何循环访问API Rest响应中的所有页面

我正在编写一个代码，可以从WooCommerce商店检索产品。API只返回100种产品，而总数量高达147种。API返回两个页面，但我似乎无法循环浏览这些页面

这是我目前的代码：

protected void btnEnviar_Click(object sender, EventArgs e)
    {
        try
        {
            string apiUrl = "https://thestore.com/wp-json/wc/v3/products?per_page=100";
            string apiUsr = "usertoken";
            string apiPwd = "passwordtoken";

            string urlRequest1 = apiUrl;
            HttpWebRequest requestWeb = (HttpWebRequest)WebRequest.Create(urlRequest1);
            requestWeb.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
            requestWeb.ContentType = "application/json";
            requestWeb.Accept = "application/json";
            requestWeb.Method = WebRequestMethods.Http.Get;
            requestWeb.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(apiUsr + ":" +apiPwd));
            requestWeb.UseDefaultCredentials = true;
            requestWeb.Proxy.Credentials = CredentialCache.DefaultCredentials;
            HttpWebResponse responseHttpWeb = (HttpWebResponse)requestWeb.GetResponse();

            Stream stream = responseHttpWeb.GetResponseStream();

            //JsonConvert.DeserializeObject<List<RetrieveMultipleResponse>>(JsonStr);
            using (StreamReader reader = new StreamReader(stream))
            {
                Stream webResponse = responseHttpWeb.GetResponseStream();
                string lector = reader.ReadToEnd();
                var mQuery = JsonConvert.DeserializeObject<List<Root>>(lector);
                int contarObjetos = mQuery.Count();
                contarItems.Text = contarObjetos.ToString();

                

                if (contarObjetos == 0)
                {
                    enviado.Text = "No existen registros";
                }
                else
                {
                    
                    foreach (var item in mQuery)
                    {
                        enviado.Text += item.id + ": " + item.name + " - " + item.status + "<br/><hr/>";

                        foreach(var elemento in item.categories)
                        {
                            enviado2.Text += elemento.id + ": " + elemento.name + "<br/><hr/>"; 
                        }
                    }
                    
                }
                
                
            }

        }
        catch (Exception ex)
        {
            enviado.Text = ex.ToString();
        }
        
    }

但是我如何从api的头文件中获取页数并动态地将其分配到循环中呢

以下是我在《邮差》上看到的标题：

所以我想，如果我能访问那个标题，并将它分配给一个对象，并在每个循环中增加，我就会实现我想要的

我一直在浏览WooCommerce的API文档，但没有关于如何执行此操作的信息，并且在JSON的响应中没有返回页数的对象

对我来说，任何帮助都是巨大的

试试以下方法：

protected void btnEnviar_Click(object sender, EventArgs e)
{
    try
    {
        string apiUrl = "https://thestore.com/wp-json/wc/v3/products?per_page=100";
        string apiUsr = "usertoken";
        string apiPwd = "passwordtoken";

        int page = 1;
        int totalPages = 0;
        int count = 0;

        do
        {
            string urlRequest = page == 1 ? apiUrl : apiUrl + $"&page={page}";

            HttpWebRequest requestWeb = (HttpWebRequest)WebRequest.Create(urlRequest);

            requestWeb.AutomaticDecompression = DecompressionMethods.GZip | DecompressionMethods.Deflate;
            requestWeb.ContentType = "application/json";
            requestWeb.Accept = "application/json";
            requestWeb.Method = WebRequestMethods.Http.Get;
            requestWeb.Headers["Authorization"] = "Basic " + Convert.ToBase64String(Encoding.Default.GetBytes(apiUsr + ":" + apiPwd));
            requestWeb.UseDefaultCredentials = true;
            requestWeb.Proxy.Credentials = CredentialCache.DefaultCredentials;
            HttpWebResponse responseHttpWeb = (HttpWebResponse)requestWeb.GetResponse();

            string totalPages2 = responseHttpWeb.Headers["X-WP-TotalPages"];

            // We don't really need to check for success. On failure it will write 0 and
            // will break the cycle
            int.TryParse(totalPages2, out totalPages);

            using (var stream = responseHttpWeb.GetResponseStream())
            using (var sr = new StreamReader(stream))
            using (var jr = new JsonTextReader(sr))
            {
                var ser = new JsonSerializer();

                var items = ser.Deserialize<List<Root>>(jr);

                if (items.Count == 0)
                {
                    if (page == 1)
                    {
                        enviado.Text = "No existen registros";
                    }
                }
                else
                {
                    count += items.Count;

                    foreach (var item in items)
                    {
                        enviado.Text += item.id + ": " + item.name + " - " + item.status + "<br/><hr/>";

                        foreach (var elemento in item.categories)
                        {
                            enviado2.Text += elemento.id + ": " + elemento.name + "<br/><hr/>";
                        }
                    }
                }
            }

            page++;
        } while (page <= totalPages);

        contarItems.Text = count.ToString();
    }
    catch (Exception ex)
    {
        enviado.Text = ex.ToString();
        contarItems.Text = string.Empty;
    }
}

protectedvoid btneviar\u单击（对象发送方，事件参数e）
{
尝试
{
字符串apiUrl=”https://thestore.com/wp-json/wc/v3/products?per_page=100";
字符串apiUsr=“usertoken”；
字符串apiPwd=“passwordtoken”；
int page=1；
int totalPages=0；
整数计数=0；
做
{
字符串URLRESQUEST=page==1？APIRL:APIRL+$“&page={page}”；
HttpWebRequest requestWeb=（HttpWebRequest）WebRequest.Create（urlRequest）；
requestWeb.AutomaticDecompression=DecompressionMethods.GZip | DecompressionMethods.Deflate；
requestWeb.ContentType=“application/json”；
requestWeb.Accept=“application/json”；
requestWeb.Method=WebRequestMethods.Http.Get；
requestWeb.Headers[“Authorization”]=“Basic”+Convert.ToBase64String（Encoding.Default.GetBytes（apiUsr+”：“+apiPwd））；
requestWeb.UseDefaultCredentials=true；
requestWeb.Proxy.Credentials=CredentialCache.DefaultCredentials；
HttpWebResponse responseHttpWeb=（HttpWebResponse）requestWeb.GetResponse（）；
字符串totalPages2=responseHttpWeb.Headers[“X-WP-TotalPages”]；
//我们真的不需要检查是否成功。失败时，它将写入0和
//将打破这个循环
int.TryParse（总页数2，总页数外）；
使用（var stream=responseHttpWeb.GetResponseStream（））
使用（var sr=新的StreamReader（stream））
使用（var jr=新的JsonTextReader（sr））
{
var ser=新的JsonSerializer（）；
var items=序列反序列化（jr）；
如果（items.Count==0）
{
如果（第==1页）
{
enviado.Text=“不存在注册表”；
}
}
其他的
{
计数+=项目。计数；
foreach（项目中的var项目）
{
enviado.Text+=item.id+“：“+item.name+”-“+item.status+”
”；
foreach（项目类别中的变量elemento）
{
enviado2.Text+=elemento.id+“：“+elemento.name+”
”；
}
}
}
}
page++；
}while（page）您是否尝试过
responseHttpWeb.Headers
？例如：
string numPages=responseHttpWeb.Headers[“X-WP-TotalPages”]；int numPages2；if（int.TryParse（numPages，out numPages2））{//Success！}
如果它提供了页数，我可以编写一些行代码来提取其他页面。是的！它返回了页数（本例中为2页）。谢谢。但是现在，我如何循环这些页面？
