CodePudding user response：

You can do this using reflection:

public static void ChangeResolution(int sizeIndex)
{
    var assembly = typeof(Editor).Assembly;
    var gameView = assembly.GetType("UnityEditor.GameView");
    var instance = EditorWindow.GetWindow(gameView);
    gameView.GetMethod("SizeSelectionCallback")!.Invoke(instance, new object[] { sizeIndex, null });
}

sizeIndex is the index of the resolution in dropdown (0 - free aspect; 1 - 800x480)
