4. Wihtin the page class file add a reference to the added web service
using MossWebServiceExample.ListService;

use the below code and you are done

ListService.Lists listService = new Lists();
listService.Credentials = System.Net.CredentialCache.DefaultCredentials;
XmlDocument xmlDoc = new System.Xml.XmlDocument();
XmlNode ndQuery = xmlDoc.CreateNode(XmlNodeType.Element, "Query", "");
XmlNode ndViewFields = xmlDoc.CreateNode(XmlNodeType.Element, "ViewFields", "");

ndViewFields.InnerXml ="";
ndQuery.InnerXml = "Specify text;

try
{
XmlNode ndListItems =
listService.GetListItems("", null, ndQuery, ndViewFields, "", null, null);
Page.Response.Write(ndListItems.InnerXml);
}
