请教高手服务器端的WebService加了用户和密码验证，客户端要连接他怎么设置才能访问其中的方法？

Question

我调用服务的某一个接口方法后 他就显示出异常(SoapHeadException)： Authorization failure
   在 System.Web.Services.Protocols.SoapHttpClientProtocol.ReadResponse(SoapClientMessage message, WebResponse response, Stream responseStream, Boolean asyncCall)\r\n   在 System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters)\r\n   在 TY.TYService.SupportInterfaceBeanService.accessMessage(accessMessage accessMessage1)  请教大家我下面的代码有错吗？            TYService.SupportInterfaceBeanService myservice = new TYService.SupportInterfaceBeanService();            
            ICredentials credentials = new NetworkCredential("lihuoming", "123456");            myservice.CookieContainer = new CookieContainer();
            myservice.Credentials = credentials;

Answer 1

webservice定义了一个继承SoapHead的类   
 public class AuthHeader:SoapHeader
    {              public string UserName;              public string Password;       }
访问时需要
 AuthHeader auth=new AuthHeader();                     WebServices webService=new WebServices();                     auth.UserName=this.txtName.Text.Trim();                     auth.Password=this.txtPwd.Text.Trim();                     webService.authHeader=auth;
类AuthHeader需要用webservice同一个定义
