Geodatabase - 判断是否处于编辑状态

时间：2022-03-14 01:41

Engine中提供IDatasetEdit来判断数据是否处于编辑状态,我们知道,在ArcMap中,进行编辑的不一定都是要素类,也可以是表,网络几何等.以下能在ArcMap中进行编辑的数据都实现了 IDatasetEdit接口:

Classes that implement IDatasetEdit

Classes	Description
	Esri Attributed Relationship Class object.
	A container for querying information about a cadastral fabric.
	A container for describing this cadastral fabric‘s feature dataset extension properties.
	Esri Feature Class object.
	Esri Feature Dataset object.
	Esri Geometric Network object.
	A container for querying information about a network dataset.
	A container for describing this network dataset‘s feature dataset extension properties.
	A container for describing this network dataset‘s workspace extension properties.
	Esri Object Class object.
	A collection of raster datasets in a Geodatabase table.
	Route event source object.
	Schematic diagram class object.
	Schematic element class object.
	Schematic in memory feature class object.
	A container for describing a street network.
	Esri Table object.
	Controls settings for the temporal feature class.
	Defines the COM coclass for the TemporalRecordSet COM object.
	Esri Topology object.
	A container for describing a utility network.
	XY event source object.

如下代码演示了判断要素类是否处于编辑状态:

1 private void IsEditing() {
2     ESRI.ArcGIS.Carto.ILayer lyr = mapCtrl_main.get_Layer(0);
3     ESRI.ArcGIS.Carto.IFeatureLayer flyr = (ESRI.ArcGIS.Carto.IFeatureLayer)lyr;
4 
5     ESRI.ArcGIS.Geodatabase.IFeatureClass fclass = flyr.FeatureClass;
6     ESRI.ArcGIS.Geodatabase.IDatasetEdit dsEdit = (ESRI.ArcGIS.Geodatabase.IDatasetEdit)fclass;
7     bool isEditing = dsEdit.IsBeingEdited();
8 }
