I'm trying to figure out how to update a layers symbology using an existing .lyr file. I can use the code below to add the layer file, but when I've already got the layer in my map all I really need to do is update the symbology.
Uri myUri = new Uri(@"K:\DSM Shared\ArcMap Symbology\10.2 Schema\Editing Symbols\GISWRKS1.WORKS.WAT_Hydrant.lyr");
Layer newLayer = LayerFactory.Instance.CreateFeatureLayer(myUri, MapView.Active.Map, LayerPosition.AddToTop);
Any guidance is appreciated.
