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;
}

[C#寫(xiě)法]
private void LabelField(IFeatureLayer pFeatureLayer,IServerContext pServerContext)
