Geodatabase - 判断是否处于编辑状态

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
AttributedRelationshipClass	Esri Attributed Relationship Class object.
CadastralFabric (esriGeoDatabaseExtensions)	A container for querying information about a cadastral fabric.
CadastralFabricFDExtension (esriGeoDatabaseExtensions)	A container for describing this cadastral fabric's feature dataset extension properties.
FeatureClass	Esri Feature Class object.
FeatureDataset	Esri Feature Dataset object.
GeometricNetwork	Esri Geometric Network object.
NetworkDataset	A container for querying information about a network dataset.
NetworkDatasetFDExtension	A container for describing this network dataset's feature dataset extension properties.
NetworkDatasetWorkspaceExtension	A container for describing this network dataset's workspace extension properties.
ObjectClass	Esri Object Class object.
RasterCatalog	A collection of raster datasets in a Geodatabase table.
RouteEventSource (esriLocation)	Route event source object.
SchematicDiagramClass (esriSchematic)	Schematic diagram class object.
SchematicElementClass (esriSchematic)	Schematic element class object.
SchematicInMemoryFeatureClass (esriSchematic)	Schematic in memory feature class object.
StreetNetwork	A container for describing a street network.
Table	Esri Table object.
TemporalFeatureClass (esriTrackingAnalyst)	Controls settings for the temporal feature class.
TemporalRecordSet (esriTrackingAnalyst)	Defines the COM coclass for the TemporalRecordSet COM object.
Topology	Esri Topology object.
UtilityNetwork	A container for describing a utility network.
XYEventSource	XY event source object.

如下代码演示了判断要素类是否处于编辑状态:

private void IsEditing() {
    ESRI.ArcGIS.Carto.ILayer lyr = mapCtrl_main.get_Layer(0);
    ESRI.ArcGIS.Carto.IFeatureLayer flyr = (ESRI.ArcGIS.Carto.IFeatureLayer)lyr;

    ESRI.ArcGIS.Geodatabase.IFeatureClass fclass = flyr.FeatureClass;
    ESRI.ArcGIS.Geodatabase.IDatasetEdit dsEdit = (ESRI.ArcGIS.Geodatabase.IDatasetEdit)fclass;
    bool isEditing = dsEdit.IsBeingEdited();
}
