Web Services 在C# Visual Studio ERCOT上使用签名的SOAP发出Web请求

我在使用SSL证书身份验证从C#代码向外部Web服务发出请求时遇到问题。当前，我从该Web服务收到错误代码500内部服务器错误作为响应。我与外部服务团队进行了讨论，他们建议我将请求作为签名的SOAP请求发送。服务器需要证书详细信息，因此我尝试将其作为签名的SOAP请求发送。我尝试将其作为Visual Studio中的服务引用添加，但在此遇到错误。Reference.cs未生成。因此我计划创建一个SOAP请求，其中包含证书的详细信息。但我面临着难以生成“wsse：Security”标记中的内容（如DigestValue、SignatureValue等）的问题。
SOAP请求：

                string nodalXml = File.ReadAllText(@"C:\Users\test\source\repos\WebRequestHelper\ERCOTWebServiceHelper\XMLFile1.xml");

            req.ContentType = "text/xml;charset=\"utf-8\"";
            req.Accept = "text/xml";
            req.Headers.Add("SOAPAction", action);
            req.Proxy = WebRequest.GetSystemWebProxy();
            //HTTP method    
            req.Method = "POST";
            return req;
        }
    }

当前我收到一个错误（错误500：内部服务器错误）。请帮助。

我在尝试使用ERCOT API时遇到了同样的问题，但我注意到Postman能够返回比HTTP 500内部服务器错误更多的信息。尝试在异常处理中添加类似以下内容，以便从响应流中获取详细信息：

catch (WebException webEx)
        {
            if (webEx.Status.Equals(WebExceptionStatus.ProtocolError))
            {
                HttpWebResponse webResp = (HttpWebResponse)webEx.Response;
                string respText = (new StreamReader(webResp.GetResponseStream())).ReadToEnd();
                LogError("error in EntryPoint: " + webResp.StatusDescription);
                LogError("output = " + respText);
            }
        }
