IFeatureWorkspace接口是在工作空間中創建對象主要使用的接口。方法：

? AllProperties MethodsDescription

	CreateFeatureClass	Creates a new standalone feature class under the workspace.//創建一個FeatureClass
	CreateFeatureDataset	Creates a new feature dataset.//創建一個FeatureDataset
	CreateQueryDef	Create a query definition object.
	CreateRelationshipClass	Creates a new relationship class.
	CreateTable	Creates a new table. //創建表
	OpenFeatureClass	Opens an existing feature class.//從工作空間中打開一個FeatureClass
	OpenFeatureDataset	Opens an existing feature dataset.
	OpenFeatureQuery	Opens a feature dataset containing a single feature class defined by the specified Query.
	OpenRelationshipClass	Opens an existing relationship class.
	OpenRelationshipQuery	The table of a relationship join query.
	OpenTable	Opens an existing table. ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ?//打開存在的表

1、創建一個FeatureClass

public IFeatureClass CreateFeatureClass ( ????string Name,IFields Fields,UID CLSID,UID EXTCLSID,?esriFeatureType FeatureType,string ShapeFieldName,string ConfigKeyword ); esriFeatureType見點擊打開鏈接 2、創建FeatureDataset

public IFeatureDataset CreateFeatureDataset (string Name,ISpatialReference SpatialReference ); 3、

public IQueryDef CreateQueryDef ( ); 4、public IFeatureClass OpenFeatureClass (string Name ); 打開一個FeatureClass(Workspace as IFeatureWorkspace).OpenFeatureClass(FeatureClassName); 創建例子：? ? ? ??///?<summary>///?創建要素類///?</summary>///?<param?name="workspace"></param>///?<param?name="featureDataset"></param>///?<param?name="featureClassName"></param>///?<param?name="fields"></param>///?<param?name="CLSID"></param>///?<param?name="CLSEXT"></param>///?<param?name="strConfigKeyword"></param>///?<returns></returns> ????????public?static?IFeatureClass?CreateFeatureClass(IFeatureDataset?featureDataset,?String?featureClassName,?IFields?fields){if?(_workSpaceInstance?==?null)?return?null;IFeatureClass?featureClass?=?null;IFeatureWorkspace?featureWorkspace?=?(IFeatureWorkspace)_workSpaceInstance;?//?assign?the?class?id?value?if?not?assigned ????????????ESRI.ArcGIS.esriSystem.UID?CLSID?=?null;ESRI.ArcGIS.esriSystem.UID?CLSEXT?=?null;string?strConfigKeyword?=?"";if?(CLSID?==?null){CLSID?=?new?ESRI.ArcGIS.esriSystem.UIDClass();CLSID.Value?=?"esriGeoDatabase.Feature";}System.String?strShapeField?=?"";//?locate?the?shape?field ????????????for?(Int32?j?=?0;?j?<?fields.FieldCount;?j++){esriFieldType?dd?=?fields.get_Field(j).Type;if?(dd?==?esriFieldType.esriFieldTypeGeometry){strShapeField?=?fields.get_Field(j).Name;}}//?finally?create?and?return?the?feature?class ????????????if?(featureDataset?!=?null){featureClass?=?featureDataset.CreateFeatureClass(featureClassName,?fields,?CLSID,?CLSEXT,?esriFeatureType.esriFTSimple,?strShapeField,?strConfigKeyword);}return?featureClass;}
