some code refactor

Before:

            PAS.UserAuths ret = new PAS.UserAuths();

            PAS.PASservicesSoapClient svc = new PAS.PASservicesSoapClient();

            var securityHeader = new PHSCredentialsHeader()

            {

                Username = _Username,

                Password = _Password

            };

            using (System.ServiceModel.OperationContextScope contextScope = new System.ServiceModel.OperationContextScope(svc.InnerChannel))

            {

                System.ServiceModel.OperationContext.Current.OutgoingMessageHeaders.Add(securityHeader);

                                     ...

After using dll:

            PAS.UserAuths ret = new PAS.UserAuths();

            PAS.PASservicesSoapClient svc = new PAS.PASservicesSoapClient();

            PHSServiceAI.PHSServiceWrapper sw = new PHSServiceAI.PHSServiceWrapper(_Username, _Password, svc.InnerChannel);           

            using (sw.cScope)

            {

                                ...

DLL Code:

namespace PHSServiceAI

{

    /// 

    /// Security Header Wrapper for PHS AI Servcies

    /// 

    public class PHSServiceWrapper

    {

        public string UserId { get; set; }

        public string Password { get; set; }

        public System.ServiceModel.OperationContextScope cScope { get; set; }

        public PHSServiceWrapper()

        {

        }

        public PHSServiceWrapper(string uName, string pw, System.ServiceModel.IContextChannel ic)

        {

            try

            {

                this.UserId = uName;

                this.Password = pw;

                PHSCredentialsHeader crdHdr;

                crdHdr = new PHSCredentialsHeader()

                {

                    Username = this.UserId,

                    Password = this.Password

                };

                cScope = new System.ServiceModel.OperationContextScope(ic);

                System.ServiceModel.OperationContext.Current.OutgoingMessageHeaders.Add(crdHdr);

            }

            catch (Exception e)

            {

                //TODO log e.Message etc.

            }

        }

    }

}
