bool success = false;

//  This example requires the Chilkat API to have been previously unlocked.
//  See Global Unlock Sample for sample code.

//  --------------------------------------------------------------------------------
//  Also see Chilkat's Online WSDL Code Generator
//  to generate code and SOAP Request and Response XML for each operation in a WSDL.
//  --------------------------------------------------------------------------------

//  This example uses a live web service at:
//  http://www.webservicex.net/uklocation.asmx
//  It gets the UK town,Postcode and County by Postcode(First Section of Post Code)

//  The SOAP XML will look like this:
//  <?xml version="1.0" encoding="utf-8"?>
//  <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>
//      <GetUKLocationByPostCode xmlns="http://www.webserviceX.NET">
//        <PostCode>string</PostCode>
//      </GetUKLocationByPostCode>
//    </soap:Body>
//  </soap:Envelope>

//  For this example's sake, we'll load the XML from a file.  We'll test using PostCode "E3".  
//  The SOAP XML for this example may be downloaded from:
//  http://www.chilkatsoft.com/testData/ukPostCodeSoap.xml
Chilkat.Xml xml = new Chilkat.Xml();
success = xml.LoadXmlFile("ukPostCodeSoap.xml");
if (success == false) {
    Debug.WriteLine(xml.LastErrorText);
    return;
}

string strXml = xml.GetXml();

int responseStatusCode;
Chilkat.Http http = new Chilkat.Http();

//  We'll need to add this in the HTTP header:
//  SOAPAction: "http://www.webserviceX.NET/GetUKLocationByPostCode"
http.SetRequestHeader("SOAPAction","http://www.webserviceX.NET/GetUKLocationByPostCode");

//  The endpoint for this soap service is:
string endPoint = "http://www.webservicex.net/uklocation.asmx";

//  Note: This particular web service was live and functioning at the time this example
//  was written.  It is possible that as time progresses, this web service will no longer
//  be availble...
Chilkat.HttpResponse resp = new Chilkat.HttpResponse();
success = http.HttpStr("POST",endPoint,strXml,"utf-8","text/xml",resp);
if (success == false) {
    Debug.WriteLine(http.LastErrorText);
    return;
}

responseStatusCode = resp.StatusCode;
//  You may wish to verify that the responseStatusCode equals 200...
Debug.WriteLine("Response Status Code: " + Convert.ToString(responseStatusCode));

//  You may examine the exact HTTP header sent with the POST like this:
Debug.WriteLine("LastHeader:");
Debug.WriteLine(http.LastHeader);

//  Examine the XML returned by the web service:
Debug.WriteLine("XML Response:");
Chilkat.Xml xmlResp = new Chilkat.Xml();
xmlResp.LoadXml(resp.BodyStr);
Debug.WriteLine(xmlResp.GetXml());
