IFeatureClass接口

ArcGIS Developer Help (ESRI.ArcGIS.Geodatabase)

IFeatureClass Interface

Provides access to members that control the behavior and properties of a feature class.

Product Availability

Available with ArcGIS Engine, ArcGIS Desktop, and ArcGIS Server.

When To Use

The IFeatureClassinterface is the main interface for getting and setting properties of a feature class. For example, use the IFeatureClass interface to get the type of feature class, get a count of features that satisfy some query, or create a new feature in the feature class. The IFeatureClass interface inherits from the IObjectClass interface.

Inherited Interfaces

Interfaces	Description
IObjectClass	Provides access to members that return information about an object class.
IClass	Provides access to members that return information about and manage the class.

Classes that implement IFeatureClass

Classes	Description
FeatureClass	Esri Feature Class object.
NAClass (esriNetworkAnalyst)	Holds features used as input and generated as output during network analysis.
RasterCatalog	A collection of raster datasets in a Geodatabase table.
RelQueryTable	An object that joins two datasets based on common data values.
