创建完文本注记后，可以选择以屏幕注记的形式加到屏幕上，也可以通过下面的方式转为注记图层要素：

 

IFeatureClass annocls = 获取注记图层  IDataset pDataset = annocls as IDataset;  ITransactions pTransactions = pDataset.Workspace as ITransactions;  pTransactions.StartTransaction();  IFDOGraphicsLayerFactory pFDOGLFactory = new FDOGraphicsLayerFactoryClass();  ILayer tmpLayer = pFDOGLFactory.OpenGraphicsLayer(pDataset.Workspace as IFeatureWorkspace, annocls.FeatureDataset, pDataset.Name);  IFDOGraphicsLayer pFDOGLayer = tmpLayer as IFDOGraphicsLayer;  IElementCollection pElementColl = new ElementCollectionClass();  pFDOGLayer.BeginAddElements();  ////每新增100个提交下，最后再提交下。防止过多转换失败  if ((pElementColl != null) && (pElementColl.Count == 100))  {      pFDOGLayer.DoAddElements(pElementColl, 0);      pFDOGLayer.EndAddElements();      pElementColl.Clear();      pTransactions.CommitTransaction();      pTransactions.StartTransaction();      pFDOGLayer.BeginAddElements();  }  if (pElementColl.Count > 0)  pFDOGLayer.DoAddElements(pElementColl, 0);  pFDOGLayer.EndAddElements();  pElementColl.Clear();  pTransactions.CommitTransaction();
