ArcEngine图层Join表后保存为shape后，shape属性表不全

caodajiefly 2011-09-22 11:16:12

麻烦大家看一下，我是用一个图层jion另一个图层的，join后，查看属性表，确实两个图层的属性信息都有

但是将join后的面图层输出后，只有原来的属性信息（join前面的属性信息），没有join后的属性信息（面和点的属性信息）。

我保存Feature class 为shape的方法如下：



private void saveAllFeature(IFeatureLayer featureLayer)



{



IFeatureClass pInputFeatureClass = featureLayer.FeatureClass;







IFeatureClass featureclass = ptable as IFeatureClass;



IDataset pInDataset = featureclass as IDataset;



IDataset pInDataset = pInputFeatureClass as IDataset;



IDatasetName pInDatasetName = pInDataset.FullName as IDatasetName;



IFeatureClassName pInFeatureClassName = pInDatasetName as IFeatureClassName;









IWorkspaceFactory pWorkspaceFactory = new ShapefileWorkspaceFactoryClass();



IWorkspace pWorkspace = pWorkspaceFactory.OpenFromFile(fileDir, 0);







IDataset pOutDataset = pWorkspace as IDataset;



IWorkspaceName pOutWorkspaceName = pOutDataset.FullName as IWorkspaceName;







IFeatureClassName pOutFeatureClassName = new FeatureClassNameClass();



IDatasetName pOutDatasetName = pOutFeatureClassName as IDatasetName;



pOutDatasetName.Name = fileName;







pOutDatasetName.WorkspaceName = pOutWorkspaceName;



//////////////////////////////////////////////////////////////////////////



IFields pOutFields, pInFields;







IFieldChecker pFieldChecker;







IField pGeoField;







IEnumFieldError pEnumFieldError = null;







pInFields = pInputFeatureClass.Fields;







pFieldChecker = new FieldChecker();



pFieldChecker.Validate(pInFields, out pEnumFieldError, out pOutFields);







String shapeFieldName = pInputFeatureClass.ShapeFieldName;







int shapeFieldIndex = pInputFeatureClass.FindField(shapeFieldName);







IField shapeField = pInputFeatureClass.Fields.get_Field(shapeFieldIndex);







IGeometryDef geometryDef = shapeField.GeometryDef;







IClone geometryDefClone = (IClone)geometryDef;







IClone outGeometryDefClone = geometryDefClone.Clone();







IGeometryDef outGeometryDef = (IGeometryDef)outGeometryDefClone;







IFeatureDataConverter featureDataConverter = new FeatureDataConverterClass();







featureDataConverter.ConvertFeatureClass(pInFeatureClassName, null, null, pOutFeatureClassName,



outGeometryDef, pOutFields, "", 1000, 0);







}
