FGDB and working with it.

Hi,
is there any way to select all FC and datasets from FileGDB? I would like to extract all elements from the path to .gdb and add them to the list. Is it possible?

Thank you
David

Hi,

You can call GetDefinitions for individual dataset types:

var fcDefinitions = geodatabase.GetDefinitions<FeatureClassDefinition>();
var tableDefinitions = geodatabase.GetDefinitions<TableDefinition>();
var datasetDefinitions = geodatabase.GetDefinitions<FeatureDatasetDefinition>();
.....
// Similar for other dataset types

// Loop through the results
foreach (var definition in datasetDefinitions)
{
Console.WriteLine(definition.GetName() + "=>" + definition.DatasetType);

definition.Dispose();

}

Just a question, I'm trying to make Layers out of it, but I don't know how to put it together to select FeatureClass and FeatureDataset.

This snippet shows you the path differences in feature datasets and feature classes.

You can get the path using featureClass.GetPath().

var fcName = featureClassDef.GetName(); using (var fc = geodatabase.OpenDataset<FeatureClass>(fcName)) { FeatureDataset featureDataset = fc.GetFeatureDataset(); if(featureDataset !=null) { // do something with feature class inside feature dataset } var path = fc.GetPath(); LayerFactory.Instance.CreateLayer(path, MapView.Active.Map); }

To filter the feature classes only inside the feature dataset you can use geodatabase.GetRelatedDefinitions() method.

foreach (var featureDatasetDef in featureDatasetDefinitions) { IReadOnlyList<Definition> datasetsInFeatureDataset = geodatabase.GetRelatedDefinitions(featureDatasetDef, DefinitionRelationshipType.DatasetInFeatureDataset); foreach(Definition datsetInFeatureDataset in datasetsInFeatureDataset) { if(datsetInFeatureDataset.DatasetType == DatasetType.FeatureClass) { using (FeatureClassDefinition featureClassDefinition = datsetInFeatureDataset as FeatureClassDefinition) { var fcName = featureClassDefinition.GetName(); using (var fc = geodatabase.OpenDataset<FeatureClass>(fcName)) { var path = fc.GetPath(); LayerFactory.Instance.CreateLayer(path, MapView.Active.Map, layerName:$"From Dataset{fcName}"); } } } } }
