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);
