How to get the full path of a layer

I am trying to programmatically create a full copy of a layer on my map in ArcMap so that the user can run tools to clean up the data without mucking with the original in case they do something wrong. I have it working in ArcPro, but, because of speed issues, I am now trying to implement my cleanup tools in ArcMap. In ArcPro, my code looks like

var lyr = _arcFac.MainMapView.Map.GetLayersAsFlattenedList()

await QuededTask.Run(() =>

{

foreach (BasicFeatureLayer fmLyr in lyr) {

var hydLayer = fmLyr as FeatureLayer;

var hydClass = hydLayer .GetFeatureClass();

var hydStore = hydClass.GetDatastore();

var hydPath = Path.Combine(hydStore.GetPath().LocalPath, hydClass.GetName());

string newFileName = $"MergeLayer.shp";

var mva = Geoprocessing.MakeValueArray(hydPath + ".shp", $@"{hydPath}" newFileName);

var res2 = Geoprocessing.ExecuteToolAync("copy_Management", mva);

}

In ArcMap, I have

IFeatureLayer hydLayer = selectedLayer[0];

var hydClass = hydLayer .FeatureClass();

var hydStore = hydClass.FeatureDataset(); //this is null

So, how do I get the full path of the selected layers? File.GetPath(selectedLayer[0]) get the correct path only if it is in the same path as the map and if you have saved the map.

Thank you,

Susan

Try this code:

Public Sub GetPath()
 ' This sample code assumes the first layer in the map is a shapefile
 Dim pMXD As IMxDocument
 Set pMXD = ThisDocument
 Dim pMap As IMap
 Set pMap = pMXD.FocusMap
 Dim pLayer As ILayer
 Set pLayer = pMap.Layer(0)
 Dim pDataset As IDataset
 Set pDataset = pLayer
 Dim sPath As String
 Let sPath = pDataset.Workspace.PathName & "\" & pDataset.Name & ".shp"
 MsgBox sPath, vbOKOnly, "Full Path"
End Sub‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍
