Turn layers on/off with C#

DonFreeman — Fri, 04 Mar 2011 14:22:15 GMT

I have some VB code which works fine to turn layers on and off. It looks something like this.

Dim layers As New List(Of Integer)()
If High_Checkbox.IsChecked Then
   layers.Add(8)
  End If

  'etc...
  Dim layer As ArcGISDynamicMapServiceLayer = TryCast(MyMap.Layers("SchoolSearch3"), ArcGISDynamicMapServiceLayer)
  layer.VisibleLayers = layers.ToArray()

I would like to convert it to C# but I get a syntax error on this line

ArcGISDynamicMapServiceLayer layer = MyMap.Layers("TitleVI") as ArcGISDynamicMapServiceLayer;

So how would this be done in C#?
Thanks

Use square brackets:

ArcGISDynamicMapServiceLayer layer = MyMap.Layers["TitleVI"] as ArcGISDynamicMapServiceLayer;

Thanks Darina. I thought I had tried that but I guess I hadn't.
