How to copy feature(s) from

#1

Hello,


I would like to know if there is a simple standard way to copy feature(s) from one layer (any type) to another layer (any type)?


thanks a lot.

Hi Jean-marie, 
  
 The code should be get all features from source layer then loop the collection and add them to target layer. 
  
 Simply like this as below: 
  
  
 InMemoryFeatureLayer inMemoryFeatureLayer = new InMemoryFeatureLayer();
            Collection<Feature> inMemoryFeatureLayerFeatures = inMemoryFeatureLayer.InternalFeatures;
            ShapeFileFeatureLayer shapeFileFeatureLayer = new ShapeFileFeatureLayer("YourFilePath");
            Collection<Feature> shapeFileFeatureLayerFeatures = shapeFileFeatureLayer.FeatureSource.GetAllFeatures(ReturningColumnsType.AllColumns);
                        
            foreach (Feature feature in shapeFileFeatureLayerFeatures)
            {
                // Add feature to the other feature layer
            }

Could be nice to have a thinkgeo standar function.

Hi Jean-marie,  
  
 If you need copy features to an InMemoryFeatureLayer, I think this code should looks better, but in fact we don’t have a standard function for that. 
  
  
ShapeFileFeatureLayer shapeFileFeatureLayer = new ShapeFileFeatureLayer(“YourFilePath”);
Collection<Feature> shapeFileFeatureLayerFeatures = shapeFileFeatureLayer.FeatureSource.GetAllFeatures(ReturningColumnsType.AllColumns);
Collection<FeatureSourceColumn> shapeFileFeatureLayerColumns = shapeFileFeatureLayer.FeatureSource.GetColumns();

InMemoryFeatureLayer inMemoryFeatureLayer = new InMemoryFeatureLayer(shapeFileFeatureLayerColumns, shapeFileFeatureLayerFeatures);

Why should we open and close the from and to feature layers when using the code below?

Hi Jean-marie,  
  
 When you try to use some APIs operate featuresource you usually need to open current layer.
