I will REPOST what I posed:

its in my above post:

If TypeOf pMap.Layer(j) Is ESRI.ArcGIS.Carto.IGroupLayer

vincentLahaye

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 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!

MichaelRobb

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

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

AnatoliiTerentiev

But if there are some composite layer?

Thank you very much!

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
