Getting raster layer path in ArcGIS Pro using C#

I am creating an ArcGIS Pro Extension. I need to know the layer's path. To get the layer path, code developed so far:

var pointLayer = MapView.Active.Map.Layers.OfType<FeatureLayer>().FirstOrDefault();
var rasterLayer = MapView.Active.Map.Layers.OfType<RasterLayer>().FirstOrDefault();
var pointLayerPath = await QueuedTask.Run(() => pointLayer.GetPath());
var rasterLayerPath = await QueuedTask.Run(() => rasterLayer.GetPath());

pointLayerPath is assigned the correct path but rasterLayerPath is assigned a null value.
The result is the same for this code also.
MapView.Active.Map.GetLayersAsFlattenedList().OfType<RasterLayer>().FirstOrDefault();

How can I get the RasterLayer path?

Hi,

I use the following code to get raster layer path:

return QueuedTask.Run<string>(() => { try { string fullSpec = string.Empty; CIMDataConnection dataConnection = pLayer.GetDataConnection(); if (dataConnection is CIMStandardDataConnection) { CIMStandardDataConnection dataSConnection = dataConnection as CIMStandardDataConnection; string sConnection = dataSConnection.WorkspaceConnectionString; var wFactory = dataSConnection.WorkspaceFactory; if (wFactory == WorkspaceFactory.Raster) { string sWorkspaceName = sConnection.Split('=')[1]; string sTable = dataSConnection.Dataset; fullSpec = Path.Combine(sWorkspaceName, sTable); } } return fullSpec; } catch (Exception ex) { System.Diagnostics.Debug.WriteLine(ex.ToString(), System.Reflection.Assembly.GetExecutingAssembly().FullName); return string.Empty; } });

It works for file based rasters and Esri GRIDs. I don't check how it works with sde stored rasters
