如何使用c#在web请求中获取Cookie？

我不熟悉c语言。我想编写以下代码将数据发布到web url:

byte[] data = Encoding.ASCII.GetBytes($"Identifier={"anyUsername"}&Password={"Password"}");
            WebRequest request = WebRequest.Create("http://users.tclnet.ir/Authentication/LogOn");
            request.Method = "POST";
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;
            using (Stream stream = request.GetRequestStream())
            {
                stream.Write(data, 0, data.Length);
            }
            string responseContent = null;
            using (WebResponse response = request.GetResponse())
            {
                using (Stream stream = response.GetResponseStream())
                {
                    using (StreamReader sr99 = new StreamReader(stream))
                    {
                        responseContent = sr99.ReadToEnd();
                    }
                }
            }
