    [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 CheckUser : System.Web.Services.WebService
    {

        /// <summary>

        /// <returns></returns>
        [WebMethod]
        public string HelloWorld()
        {
            return "Hello World";
        }

        public MySoapHeader soapHead = new MySoapHeader();

        /// <summary>

        [SoapHeader("soapHead")]
        [WebMethod]
        public bool GetUserInfo(int UserID, string UserName, out string msg)
        {

            string deUserName = EncryptHelper.Decrypt(UserName, "jjjyzy");
            msg = string.Empty;
            if (!soapHead.IsValid(out msg))
            { return false; }

            else
            {
                return checkCount(UserID, deUserName);

            }

        {
            string sqlStr = "select table where id=userid and Username= username";

            return true;
        }

    }

    /// <summary>
    /// soaphead验证的方法帐号密码ly(重写一个类)

    public class MySoapHeader : System.Web.Services.Protocols.SoapHeader
    {
        public string WsUserName
        { get; set; }
        public string WsPwd
        { get; set; }

        public MySoapHeader()
        {

        }

        public bool IsValid(out string msg)
        {
            return IsValid(WsUserName, WsPwd, out msg);
        }

        {//, out string msg
            msg = string.Empty;
            if (wsusername == "ly" & wspwd == "ly")
            { msg = "您有权调用"; return true; }

            else { msg = "您无权调用"; return false; }
        }

    }
}
