SDE要素类导出为shp格式文件

与导出到PGDB的方法相似，shapefile没有Annotation featureclass,所以用以下这一方法就够

Private Sub ExportFeatureClass()Sub ExportFeatureClass(pFeatWorkspace As IFeatureWorkspace, pGeometry As IGeometry, pFCN() As String, OutputLocation As String)

           Set pWorkspaceName = New WorkspaceName

           pWorkspaceName.WorkspaceFactoryProgID = pProgID

           Set pOutDatasetName.WorkspaceName = pWorkspaceName


           Set pExportOp = New ExportOperation

           pExportOp.ExportFeatureClass pInDsName, Nothing, pSelectionSet, Nothing, pOutDatasetName, 0
          
              
       
        Set pFeatCLS = Nothing
