How to create a feature class?

nadja

This might appear really basic, but I only manage to create a query feature class from my dockpane using this code:

await QueuedTask.Run(() => LayerFactory.Instance.CreateLayer<FeatureLayer>(flyrCreatnParam, MapView.Active.Map));

  that's nice, but query feature class don't show the area and length of a feature. however we need that, which is why we want to create a feature class instead. the data lies on a postgis/postgresql database. how can I create a feature class using the ArcGIS Pro .NET SDK?

never mind, I found half of the solution:

using (Geodatabase geodatabase = new Geodatabase(new DatabaseConnectionFile(new Uri(sde_path))))
{

    //ArcGIS.Desktop.Framework.Dialogs.MessageBox.Show(featureClassDefinition.ToString(), "featureClassDefinition");
    using (FeatureClass fc = geodatabase.OpenDataset<FeatureClass>("parcs."+name))
    {
        // Create the feature layer creation parameters
        FeatureLayerCreationParams layerCreationParams = new FeatureLayerCreationParams(fc)
        {
            // Optionally set additional properties
            Name = name
        };


        // Create the feature layer and add it to the active map
        await QueuedTask.Run(() => LayerFactory.Instance.CreateLayer<FeatureLayer>(layerCreationParams, MapView.Active.Map));
    }
}

only thing is, it doesnt really behave like a Enterprise Geodatabase Feature Class. Neither the attribute Shape_Length nor Shape_Area are in the attribute table and there still is a strange query in the layer properties (SELECT attr1,attr2,attr3,...,attrn FROM schema.name).
