通过ArcEngine获得注记的信息

访问注记层的元素和访问其他类型的地物一样，都需要通过IFeatureClass接口的Search函数获得一个IFeatureCursor对象，通过这个对象来遍历FeatureClass。

处理注记的代码为：

            if (pFeature.FeatureType == esriFeatureType.esriFTAnnotation)
            {
                IAnnotationFeature pAnnoFeature = pFeature as IAnnotationFeature;
                ITextElement pTextElement = pAnnoFeature.Annotation as ITextElement;
                string a = pTextElement.Text;
                double b = pTextElement.Symbol.Size;
                double c = pTextElement.Symbol.Angle;               
                IElement pElement = pAnnoFeature.Annotation as IElement;
                esriGeometryType geoType = pElement.Geometry.GeometryType;
                IPoint pPoint = pElement.Geometry as IPoint;
                double x = 0, y = 0;
                pPoint.QueryCoords(out x, out y);
                int cc = 0;

                return;
            }
