[mapguide-users] Determine if Layer is a Raster Layer

[adnan.c]

Thank you both for the responses, I managed to get it working using both the
XML file and the code Andy gave.  

Here it is in C# 

            map.Open(resService, mapName);

            MgLayerCollection layers = map.GetLayers();

            ArrayList layerNames = new ArrayList();

            for (int i = 0; i < layers.GetCount(); i++)
            {
                MgLayer layer = (MgLayer)layers.GetItem(i);

                string layerType = layer.GetFeatureGeometryName();

                //"Image" for the Autodesk raster provider and "Raster" for
the GDAL provider. 
                if (layerType != "Image" && layerType != "Raster")
                {
                    layerNames.Add(layer.GetName());
                }
            }
