AE实现矢量图层标注属性

添加引用ESRI.ArcGIS.Carto

1.获取图层

 IGeoFeatureLayer pFtrLayer = m_pLayer as IGeoFeatureLayer;

2.初始化标注属性集合

 IAnnotateLayerPropertiesCollection pAnnoProps = pFtrLayer.AnnotationProperties;
 pAnnoProps.Clear();

3.选择要标注的属性字段

 ILabelEngineLayerProperties item = new LabelEngineLayerPropertiesClass();
 item.Expression = "[要显示属性的字段名]";
 item.Symbol = this.btnFont.Tag as ITextSymbol;//可不定义项

 IAnnotateLayerProperties pAnnoLayerProps = item as IAnnotateLayerProperties;
 pFtrLayer.DisplayAnnotation = this.checkBox1.Checked;//是否显示标注
 pAnnoLayerProps.AnnotationMaximumScale = ;//可不定义项
 pAnnoLayerProps.AnnotationMinimumScale = ;//可不定义项
            

4.在标注属性集合中添加此字段实现标注属性

 pAnnoProps.Add(pAnnoLayerProps);//可以标注多个属性字段
