[Unity3D]通过反射方式获取Game View当前选择的分辨率

System.Type T = System.Type.GetType("UnityEditor.GameView,UnityEditor");
System.Reflection.MethodInfo GetMainGameView = T.GetMethod("GetMainGameView", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Static);
System.Object Res = GetMainGameView.Invoke(null, null);
var gameView = (UnityEditor.EditorWindow)Res;
var prop = gameView.GetType().GetProperty("currentGameViewSize", System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance);
var gvsize = prop.GetValue(gameView, new object[0] { });
var gvSizeType = gvsize.GetType();

var debug_h = (int)gvSizeType.GetProperty("height", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance).GetValue(gvsize, new object[0] { });
var debug_w = (int)gvSizeType.GetProperty("width", System.Reflection.BindingFlags.Public | System.Reflection.BindingFlags.Instance).GetValue(gvsize, new object[0] { });

以上代码可获取Game View中当前选择的分辨率，而非Using resolution。取到的值可用于动态设置NGUI组件（如UIScrollView）的参数等。
