C# Newbie - Using SOAP to send SMS

Hi,

I'm new to C# and would greatly appreciate some assistance in puting together a simple form a which would allow me to send an SMS via SOAP.

The technical documentation can be found here http://www.aql.com/site/devel_soap.php

I've made a reference to the WSDL file and now have the following .cs, copy attached in .txt file.

An example I've been given for using the above was: -

VB Code:

public void sendansms()
{
 
 string [] destarr = new string[1];
 destarr[0] = "44711111111";
 destarr[1] = "44722222222";
 cpLatestBrief.authValue = new auth();
 cpLatestBrief.authValue.username = "myusername";
 cpLatestBrief.authValue.password = "mypassword";
 string creditsused;// = new string("");
 
 string outdesr;// = new string("");
 
 System.DateTime dt = DateTime.Now;
 testwebserv1.WebReference.callbackelement cbe = new callbackelement();
 cbe.callbackurl = "http://url.com";
 cbe.callbacktype = testwebserv1.WebReference.callbacktypeoptions.HTTPGET;
 if (cpLatestBrief != null)
 {
  try
  {
   //MessageBox.Show("You must enter a name.", "Name Entry Error",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
   cpLatestBrief.SoapSendSms(destarr,"orig",messagetext.Text,testwebserv1.WebReference.mtype.text,"2",dt,false,cbe,out creditsused,out outdesr);
   MessageBox.Show(creditsused, "Credits used",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
  }
  catch(SoapHeaderException e)
  {
 
   MessageBox.Show(e.Message, "Authentication error",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
  }
  catch(SoapException e)
  {
 
   System.Xml.XmlNode node = e.Detail;
 
   string errorcode = e.Detail.FirstChild.InnerText; 
   string errortext = e.Detail.FirstChild.NextSibling.InnerText;
 
 
   if(errorcode == "DESTERROR-INVALIDNUMBERS")
    MessageBox.Show(e.Message, "Name Entry Error",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
   else if(errorcode == "MESSAGE-NOTSUPPLIED")
    MessageBox.Show(e.Message, "Name Entry Error",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
   else
    MessageBox.Show(errorcode+e.Message+"  "+errortext, "Name Entry Error",MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
  }
  return;
 }
 else
  return;
}

Looking at the example, what do I need to do/change to get it working with the Class?

Sorry if this is a lame question, but I'm new to C# Classes.

Regards
