IDataset FullName property always null

[JosephSaltenberger]

I am triyng to access the FullName property of IDataset, but FullName is always null (incidentsDataset.FullName below)

Here is the code I'm using:

            IMxDocument mxdoc = ArcMap.Application.Document as IMxDocument;
            IMap map = mxdoc.FocusMap;
            IEnumLayer enumLayer = map.Layers;
            ILayer layer = enumLayer.Next();
            IFeatureLayer2 incidentsFLayer = null;

            while (layer != null)
            {
                if (layer.Name == "Incidents" && layer is IFeatureLayer2)
                {
                    incidentsFLayer = layer as IFeatureLayer2;
                }


                layer = enumLayer.Next();
            }

                IFeatureClass incidentsFC = incidentsFLayer.FeatureClass as IFeatureClass;
                IDataset incidentsDataset = incidentsFC as IDataset;
                IFeatureClassName incidentsFCName = incidentsDataset.FullName as IFeatureClassName;

Thanks.

Hi, do you mean the IName object returned by incidentsDataset.FullName  is null, or its NameString is empty? I tested your code snippet, and was able to get a valid IName object as well as a valid IFeatureClassName after casting. Though the NameString is empty (which is a known issue http://resources.arcgis.com/en/help/arcobjects-net/componenthelp/index.html#//00420000014z000000 ), we can use the IName.Open method to open the feature class. if you would like to get the name string, you may consider using IDataset.Name property instead.
