using System.Data.SqlClient;
using System.Data;
using System.Web.Configuration;
using System.Xml;
 

namespace usingparameterwebservice
{
    /// <summary>
    /// Summary description for mywebservice
    /// </summary>
    [WebService(Namespace = "create_request")]
    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]
    [System.ComponentModel.ToolboxItem(false)]
    // To allow this Web Service to be called from script, using ASP.NET AJAX, uncomment the following line.
    // [System.Web.Script.Services.ScriptService]
    public class Service1 : System.Web.Services.WebService
    {
        string constring = WebConfigurationManager.ConnectionStrings["Name"].ToString();
        SqlConnection conn;
        SqlCommand comm;


[WebMethod(Description = "Просмотр всех заявок")]
        public XmlElement Selectall()
        {

            SqlConnection myConn = new SqlConnection(constring);
            SqlDataAdapter myData = new SqlDataAdapter("allreq", myConn);
            myData.SelectCommand.CommandType = CommandType.StoredProcedure;
                        DataSet ds = new DataSet();
            myData.Fill(ds);
            ds.Tables[0].TableName = "requests";
            XmlDataDocument xmldata = new XmlDataDocument(ds);
            XmlElement xmlElement = xmldata.DocumentElement;
