代碼修改Webservice的地址，支援同步和非同步方式

非同步方式是自訂一個類，繼承你引用的Webservice類，實現給某個屬性賦值

public class MasterService : MasterDataServiceSoapClient    {        public MasterService()            : base()        {            try            {                string uri = string.Format("http://{0}:{1}/{2}", "localhost", "1111", "MasterDataService.asmx");                base.Endpoint.Address = new System.ServiceModel.EndpointAddress(new Uri(uri) { });            }            catch (Exception ex)            {                throw ex;            }        }    }    

同步方式，也是繼承你引用的Webservice類，重新賦值某個屬性
class ServiceProxy : ScanDemo.WS.Service    {        public ServiceProxy()        {            ServiceProtocol sp = new ServiceProtocol();            sp.LoadConfigs();            Url = string.Format("http://{0}:{1}/ScanDemo.WS/Service.asmx", sp.Server, sp.Port);        }    }
