Possibilities to include a SOAP interface in C# WinForm.

Question

Hello,

What is the best way to create a SOAP request in C#?
Can i simulate the answers? If so, what is the best way?
Can I ask the customer if they have a WSDL file. Would it be easier then? Such a file, can it be created easily? I don't know, never done it before.

How would I have to include it in my C# WinForms, desktop project?

Do you have a sample code for me. THANKS.

You can use HttpWebRequest
A test with the game LOTRO, WSDL : https://gls.lotro.com/GLS.DataCenterServer/Service.asmx?WSDL
where I send the command GetDatacenters (in "SOAPAction") to get a list of LOTRO servers :

HttpWebRequest httpWebRequest = ((HttpWebRequest)(WebRequest.Create("https://gls.lotro.com/GLS.DataCenterServer/Service.asmx")));
httpWebRequest.Method = "POST";
string sPostData = @"<soap:Envelope xmlns:xsi=""http://www.w3.org/2001/XMLSchema-instance"" xmlns:xsd=""http://www.w3.org/2001/XMLSchema"" xmlns:soap=""http://schemas.xmlsoap.org/soap/envelope/"">
    <soap:Body>
        <GetDatacenters xmlns=""http://www.turbine.com/SE/GLS"">
            <game>LOTRO</game>
        </GetDatacenters>
    </soap:Body>
</soap:Envelope>";
byte[] byteArray = Encoding.UTF8.GetBytes(sPostData);
// httpWebRequest.ContentType = "application/x-www-form-urlencoded";
httpWebRequest.ContentType = "text/xml; charset=utf-8";
httpWebRequest.ContentLength = byteArray.Length;
httpWebRequest.UserAgent = "Test";
Stream dataStream = httpWebRequest.GetRequestStream();
dataStream.Write(byteArray, 0, byteArray.Length);
dataStream.Close();

httpWebRequest.Headers.Add(HttpRequestHeader.AcceptEncoding, "txt");
// httpWebRequest.Headers.Add(HttpRequestHeader.UserAgent, "Test");
httpWebRequest.Headers.Add("SOAPAction", "http://www.turbine.com/SE/GLS/GetDatacenters");

WebResponse webResp = httpWebRequest.GetResponse();
Console.WriteLine("Web response : {0}",((HttpWebResponse)(webResp)).StatusDescription);
using (Stream str = webResp.GetResponseStream())
{
    StreamReader streamReader = new StreamReader(str);
    string responseFromServer = streamReader.ReadToEnd();
    Console.WriteLine(responseFromServer);
}
webResp.Close();
