C# ArcEngine 二次开发
添加相关代码： private void axMapControl1_OnMouseDown(object sender, ESRI.ArcGIS.Controls.IMapControlEvents2_OnMouseDownEvent e) { if (this.toolStripBtnQuery.Checked == true) //如果查询比较频繁，此类变量可以设置成类级别 { ILayer pLayer; IFeatureLayer pFL; IFeatureSelection pFeatureSelection; IEnvelope pEnv; IGeometry pGeometry; ISpatialFilter pSpatialFilter; ISelectionSet pSelectionSet; IEnumIDs pEnumIDs; IFeature pFeature;
