ArcGIS中IFeatureDataConverter接口的ConvertFeatureClass方法例子

  shp转换为 featureclass:
public void ConvertShapefileToFeatureClass()
        {
            // Create a name object for the source (shapefile) workspace and open it.
            IWorkspaceName sourceWorkspaceName = new WorkspaceNameClass
            {
                WorkspaceFactoryProgID = “esriDataSourcesFile.ShapefileWorkspaceFactory”,
                PathName = @”C:\Data\Shapefiles”
            };
            IName sourceWorkspaceIName = (IName)sourceWorkspaceName;
            IWorkspace sourceWorkspace = (IWorkspace)sourceWorkspaceIName.Open();
            // Create a name object for the target (file GDB) workspace and open it.
            IWorkspaceName targetWorkspaceName = new WorkspaceNameClass
            {
                WorkspaceFactoryProgID = “esriDataSourcesGDB.FileGDBWorkspaceFactory”,
                PathName = @”C:\Data\Public.gdb”
            };
            IName targetWorkspaceIName = (IName)targetWorkspaceName;
            IWorkspace targetWorkspace = (IWorkspace)targetWorkspaceIName.Open();
            // Create a name object for the source dataset.
            IFeatureClassName sourceFeatureClassName = new FeatureClassNameClass();
            IDatasetName sourceDatasetName = (IDatasetName)sourceFeatureClassName;
            sourceDatasetName.Name = “Can_Mjr_Cities”;
            sourceDatasetName.WorkspaceName = sourceWorkspaceName;
            // Create a name object for the target dataset.
            IFeatureClassName targetFeatureClassName = new FeatureClassNameClass();
            IDatasetName targetDatasetName = (IDatasetName)targetFeatureClassName;
            targetDatasetName.Name = “Cities”;
            targetDatasetName.WorkspaceName = targetWorkspaceName;
            // Open source feature class to get field definitions.
            IName sourceName = (IName)sourceFeatureClassName;
            IFeatureClass sourceFeatureClass = (IFeatureClass)sourceName.Open();
            // Create the objects and references necessary for field validation.
            IFieldChecker fieldChecker = new FieldCheckerClass();
            IFields sourceFields = sourceFeatureClass.Fields;
            IFields targetFields = null; IEnumFieldError enumFieldError = null;
            // Set the required properties for the IFieldChecker interface.
            fieldChecker.InputWorkspace = sourceWorkspace;
            fieldChecker.ValidateWorkspace = targetWorkspace;
            // Validate the fields and check for errors.
            fieldChecker.Validate(sourceFields, out enumFieldError, out targetFields);
            if (enumFieldError != null)
            {
                // Handle the errors in a way appropriate to your application.
                Console.WriteLine(“Errors were encountered during field validation.”);
            }    // Find the shape field.
            String shapeFieldName = sourceFeatureClass.ShapeFieldName;
            int shapeFieldIndex = sourceFeatureClass.FindField(shapeFieldName);
            IField shapeField = sourceFields.get_Field(shapeFieldIndex);
            // Get the geometry definition from the shape field and clone it.
            IGeometryDef geometryDef = shapeField.GeometryDef;
            IClone geometryDefClone = (IClone)geometryDef;
            IClone targetGeometryDefClone = geometryDefClone.Clone();
            IGeometryDef targetGeometryDef = (IGeometryDef)targetGeometryDefClone;
            // Cast the IGeometryDef to the IGeometryDefEdit interface.
            IGeometryDefEdit targetGeometryDefEdit = (IGeometryDefEdit)targetGeometryDef;
            // Set the IGeometryDefEdit properties.
            targetGeometryDefEdit.GridCount_2 = 1;
            targetGeometryDefEdit.set_GridSize(0, 0.75);
            // Create a query filter to only select cities with a province (PROV) value of ‘NS.’
            IQueryFilter queryFilter = new QueryFilterClass();
            queryFilter.WhereClause = “PROV = ‘NS'”;
            queryFilter.SubFields = “Shape, NAME, TERM, Pop1996”;
            // Create the converter and run the conversion.
            IFeatureDataConverter featureDataConverter = new FeatureDataConverterClass();
            IEnumInvalidObject enumInvalidObject = featureDataConverter.ConvertFeatureClass
                (sourceFeatureClassName, queryFilter, null, targetFeatureClassName,
                targetGeometryDef, targetFields, “”, 1000, 0);    // Check for errors.
            IInvalidObjectInfo invalidObjectInfo = null; enumInvalidObject.Reset();
            while ((invalidObjectInfo = enumInvalidObject.Next()) != null)
            {
                // Handle the errors in a way appropriate to the application.
                Console.WriteLine(“Errors occurred for the following feature: {0}”,
                    invalidObjectInfo.InvalidObjectID);
            }
        }
