You can loop through all layers and check names.

Example in vb.net:

        ' Enumerate layers
        pEnumLayers = pMap.Layers
        pEnumLayers.Reset()
        pLayer = pEnumLayers.Next()

        Do Until pLayer Is Nothing
                      If pFLayer.Name = [layer name] Then
                        Exit Do
                    End If
            pLayer = pEnumLayers.Next
        Loop

But if there are some composite layer?

The imap.layers method has a recursive boolean argument as the second argument. That looks into composite layers.

You can check if its a group layer, then cycle through the composite layers within that group.

example here:

 For j = 0 To pMap.LayerCount - 1
                        

                        GetName = pMap.Layer(j).Name 
                       
                        'One level in
                        If TypeOf pMap.Layer(j) Is ESRI.ArcGIS.Carto.IGroupLayer Then

                            pCompositeLayer = pMap.Layer(j)

                            For g = 0 To pCompositeLayer.Count - 1 'cycle through the composite layer

                                'GET THE NAME of each layer here

                            Next

                        End If
                    Next

I can't find how to define that layer is group or composite layer in c#.
if (map.get_Layer(i).GetType() == ESRI.ArcGIS.Carto.IGroupLayer ??? ) ...
Can anybody help? Thanks!

hi,

if I remember it's :

if (map.get_Layer(i) is ESRI.ArcGIS.Carto.IGroupLayer)

you can use this link to compare VB and C#, if you need to translate code :

I will REPOST what I posed:

its in my above post:
