Remove() is expecting a MgLayerBase object, you are passing in a string.
Hence the compilation error.
Maybe try something like this instead:
MgMap map = new MgMap(siteConnection);
map.Open(mgMapName);
MgLayerCollection layerCol = map.GetLayers();
string layerName = "myLayer";
MgLayer layerToRemove = null;
foreach(MgLayer layer in layerCol)
{
if(layer.Name == layerName)
{
layerToRemove = layer;
break;
}
}
if(layerToRemove != null)
{
layerCol.Remove(layerToRemove);
}
