VC调用带有Soap Header的C#写的普通WebService(.net2.0)解决办法

using System;using System.Collections.Generic;using System.Web;using System.Web.Services;using System.Web.Services.Protocols;namespace Test1{    [Serializable]    public class AuthHeader : SoapHeader    {        private string _username;        private string _password;        public string UserID        {            get { return _username; }            set { _username = value; }        }        public string Password        {            get { return _password; }            set { _password = value; }        }    }    /// <summary>    /// WebService1 的摘要说明    /// </summary>    [WebService(Namespace = "http://tempuri.org/")]    [WebServiceBinding(ConformsTo = WsiProfiles.BasicProfile1_1)]    [System.ComponentModel.ToolboxItem(false)]    // 若要允许使用 ASP.NET AJAX 从脚本中调用此 Web 服务，请取消对下行的注释。    // [System.Web.Script.Services.ScriptService]    public class WebService1 : System.Web.Services.WebService    {        public AuthHeader theHeader;        [WebMethod]        public AuthHeader Dummy() { return null; }        [WebMethod(Description = "QueryRuntimeCommand.")]        //[SoapHeader("theHeader", Direction = SoapHeaderDirection.In)]        public string QueryRuntimeCommand(string TaskWorkingID, out string RuntimeCommand)        {            string ErrText = "QuerySuccess";            RuntimeCommand = "Start";            if (theHeader == null || theHeader.UserID == null)                return "Unauthenticated";            if (theHeader.UserID != "wawa")                return "Unauthenticated";            return ErrText;        }    }}
