LoadXML Add Parameters

Question

I'm doing LoadXML, but I need to add a field from the form but I couldn't,

    XmlDocument soapEnvelopeDocument = new XmlDocument();
soapEnvelopeDocument.LoadXml(
    @"<?xml version=""1.0"" encoding=""utf-8""?>
    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
        <soap:Body>
            <Servis5001>
                <Kodu>abcdefg</Kodu>
                <Sifre>123456789</Sifre>
                <HesKodu>TXBHesKodu.Text</HesKodu>
            </Servis5001>
        </soap:Body>
    </soap:Envelope>");
 
return soapEnvelopeDocument;

I need to add the TXBHESKodu.Text from the form to the <HesKodu> field here. I think I couldn't make the upper quotation marks added into the file.

Can you show me how to do it?

Answer 1

Here are two ways you could do that. The first being the simplest. Just use string formatting like this (note the $ sign before your @ sign):

XmlDocument soapEnvelopeDocument = new XmlDocument();
            soapEnvelopeDocument.LoadXml(
                $@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdefg</Kodu>
                                <Sifre>123456789</Sifre>
                                <HesKodu>{TXBHesKodu.Text}</HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

The second method uses the XML Dom to add the text into the element. We find the element using the XPath syntax:

var xmlDocument = GetXmlDocument(@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdefg</Kodu>
                                <Sifre>123456789</Sifre>
                                <HesKodu></HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

            XmlNode HesKodu = xmlDocument.SelectSingleNode("//Servis5001/HesKodu");

            HesKodu.InnerText = TXBHesKodu.Text;

You would be better off letting Visual Studio handle all the SOAP stuff for you. Take a look at adding a reference to a SOAP Web Service Reference (right click on project and Add => Web Service Reference). You can simply enter the url with ?wsdl at the end and it will generate everything you need to consume the web service.

You can use the url in a webbrowser too. If you have access to the service you can simply enter the url in the addressbar and press Enter. It should give you a description of the service and how to consume it.

Method Usage Error When I Want to Add TXT HesKodu.Text

private static XmlDocument CreateSoapEnvelope()
        {
            XmlDocument soapEnvelopeDocument = new XmlDocument();
            soapEnvelopeDocument.LoadXml(
                $@"<?xml version=""1.0"" encoding=""utf-8""?>
                    <soap:Envelope xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
                        <soap:Body>
                            <Servis5001>
                                <Kodu>abcdef</Kodu>
                                <Sifre>abcdef</Sifre>
                                <HesKodu>{TXBHesKodu.Text}</HesKodu>
                            </Servis5001>
                        </soap:Body>
                    </soap:Envelope>");

            return soapEnvelopeDocument;
        }

I also tried the Service References Process But I Didn't Know How To Request

string Kodu = "Kodu";
string Sifre = "Sifre";
string HesKodu = "HesKodu";

TOBBHesKoduSorgulamaServices.Servis5001Request S5001R = new TOBBHesKoduSorgulamaServices.Servis5001Request();
S5001R.Kodu = Kodu;
S5001R.Sifre = Sifre;
S5001R.HesKodu = HesKodu;

TOBBHesKoduSorgulamaServices.Servis5001Response S5001Response = ?

Which One Is Right For Me? Waiting for your support, good work ...
