In ArcGIS Pro SDK, how do you get the position of a found layer in a map?

[PascalVezina]

...

Layer myLayer = null;

String sName = "ABC123";

Map map = MapView.Active.Map;

IEnumerable<Layer> matches = map.GetLayersAsFlattenedList().Where(l => l.Name.IndexOf(sName, StringComparison.CurrentCultureIgnoreCase) >= 0);

int index = 0;

if (matches.Count() == 1)
{
myLayer = matches.FirstOrDefault();

//index =  position???
map.RemoveLayer(myLayer);

}

How do you insert it at the same location I originally found it ?

myLayer = LayerFactory.Instance.CreateGroupLayer(MapView.Active.Map, index, sName);

Thanks,

By 'position' I'm assuming you are referring to the position in the Layers collapsible group in the Contents pane.

You can find the index by iterating over the layer list MapView.Map.Layers via a for or foreach loop.

for(int index = 0; index < MapView.Map.Layers.Count; index++)
   if (myLayer == MapView.Map.Layers[index])
      return index;

Also when I did something similar I found a problem in SDK version 2.4 where LayerFactory.Instance.CreateGroupLayer() would only add the layer group to the 2D layers list, which may not be what you want if working with a 3D scene. You will have to add it as its own layer.
