(PowerBuilder) Duplicate TLS 1.2 SOAP Request that uses .NET HttpWebRequest

This example shows how to duplicate a SOAP request that uses .NET's HttpWebRequest and requires TLS 1.2.

        string xmlRequest = "...envelope..."

        System.Net.ServicePointManager.SecurityProtocol = (SecurityProtocolType)3072;

        string url = "https://www3.gsis.gr/webtax2/wsgsis/RgWsPublic/RgWsPublicPort?WSDL";
        HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
        req.Method = "POST";
        req.ContentType = "text/xml;charset=UTF-8";

        byte[] reqBytes = new System.Text.UTF8Encoding().GetBytes(xmlRequest);

        req.ContentLength = reqBytes.Length;

        try {
            using (System.IO.Stream reqStream = req.GetRequestStream()) {
                reqStream.Write(reqBytes, 0, reqBytes.Length);
                reqStream.Flush();
                reqStream.Close();
            }

        } catch (Exception ex) {
            actionLogger.AddError(ex.Message, null);
            actionLogger.Validate();
        }

        string xmlResponse = null;
        using (HttpWebResponse resp = (HttpWebResponse)req.GetResponse()) {
            try {
                using (System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream())) {
                    xmlResponse = sr.ReadToEnd();
                    sr.Close();
                }
            } catch (Exception ex) {
                actionLogger.AddError(ex.Message, null);
                actionLogger.Validate();
            } finally {
                resp.Close();
            }
        }
