打开arcims的数据

需要用arcims的administrator建立一个featureservice服务，服务名为country
IIMSServiceDescription imsdsc = new IMSServiceNameClass();    
       imsdsc.URL = "http://su";         //su 机器名
  imsdsc.Name = "country";           //服务名
imsdsc.ServiceType = acServiceType.acFeatureService;    //featureservice服务        IWorkspaceFactory wf = new IMSWorkspaceFactoryClass();      
     IFeatureWorkspace w = wf.Open(imsdsc.ConnectionProperties, 0) as IFeatureWorkspace;         
  IFeatureClass Fcls = w.OpenFeatureClass("counties");        
   FeatureLayer featureLayer = new FeatureLayer();          
 featureLayer.FeatureClass = Fcls;        
   axMapControl1.AddLayer(featureLayer);   
        axMapControl1.Refresh();
