IMapDescription mapdescription = webMap.MapDescription;
webMap.ManageLifetime(mapdescription); 

    ILayerDescriptions layerdec = mapdescription.LayerDescriptions;

    for(int i=0;i < mapdescription.LayerDescriptions.Count; i++)
{
    ILayerDescription onelayerdesc = layerdec.get_Element(i)； 
    onelayerdesc.Visible = true;
}  

ArcGIS Server開發——標注

[C#寫法]
private void LabelField(IFeatureLayer pFeatureLayer,IServerContext pServerContext)
  { 
   IGeoFeatureLayer pGeoFeatureLayer = pFeatureLayer as IGeoFeatureLayer;
   pGeoFeatureLayer.AnnotationProperties.Clear();
   IAnnotateLayerPropertiesCollection pAnnoLayerPropsColl = pGeoFeatureLayer.AnnotationProperties;
   ILabelEngineLayerProperties pLabelEngine;
   
   pLabelEngine = pServerContext.CreateObject("esriCarto.LabelEngineLayerProperties") as     ILabelEngineLayerProperties;
   pLabelEngine.Expression = "[Field]";
   IAnnotateLayerProperties pAnnoLayerProps = pLabelEngine as IAnnotateLayerProperties;
   pAnnoLayerPropsColl.Add(pAnnoLayerProps);
   pGeoFeatureLayer.DisplayAnnotation = true;
