arcengine标注转注记

只是将在arcmap中添加注记的方式模拟了一遍，因此，首先显示标注（Label），而后将其转换为注记（Annotation）（Convert Label To Annotation）

/*****************************************************/

SHP文件不支持标注！

public void ShowLabels(IMap pMap,string pDisplayField,int index)
        {
            ILayer pLayer = pMap.get_Layer(index);
            IFeatureLayer pFeatureLayer = pLayer as IFeatureLayer;
            IGeoFeatureLayer pGeoFeatureLayer = pFeatureLayer as IGeoFeatureLayer;
            pGeoFeatureLayer.DisplayField = pDisplayField;
            pGeoFeatureLayer.DisplayAnnotation = true;
        }
        public void ConvertLabelToAnnotation(IMap pMap,int layerindex,bool featureLinked,string AnnoName)
        {
            IConvertLabelsToAnnotation pConvertLabelToAnnotation = new ConvertLabelsToAnnotationClass();
            ITrackCancel pTrackCancel = new CancelTrackerClass();
            pConvertLabelToAnnotation.Initialize(pMap, esriAnnotationStorageType.esriDatabaseAnnotation, esriLabelWhichFeatures.esriAllFeatures, true, pTrackCancel, null);
            ILayer pLayer = pMap.get_Layer(layerindex);

            IGeoFeatureLayer pGeoFeatureLayer = pLayer as IGeoFeatureLayer;
            if (pGeoFeatureLayer == null) return;
            IFeatureClass pFeatureClass = pGeoFeatureLayer.FeatureClass;
            IDataset pDataset = pFeatureClass as IDataset;
            IWorkspace pWorkspace = pDataset.Workspace;
            IWorkspaceEdit pWorkspaceEdit = pWorkspace as IWorkspaceEdit;
            IFeatureWorkspace pFeatureWorkspace = pDataset.Workspace as IFeatureWorkspace;
            pConvertLabelToAnnotation.AddFeatureLayer(
                pGeoFeatureLayer,
                pGeoFeatureLayer.Name + "_"+AnnoName,
                pFeatureWorkspace,
                pFeatureClass.FeatureDataset,
                featureLinked,
                false,
                false,
                true,
                true,
                "");
            pConvertLabelToAnnotation.ConvertLabels();
            IEnumLayer pEnumLayer = pConvertLabelToAnnotation.AnnoLayers;
            pGeoFeatureLayer.DisplayAnnotation = false;
            pMap.AddLayers(pEnumLayer, true);
            IActiveView pActivew = pMap as IActiveView;
            pActivew.Refresh();
        }

实现简单，复制保存cs文件就可用，Visual Studio 2010 +ArcEngine 10.1.
