C# 二次开发 映射的方式获取UIApplication

public override Result OnStartup(UIControlledApplication application)中需要用到UIApplication，可以通过映射的方式获取。

var flag = System.Reflection.BindingFlags.NonPublic | System.Reflection.BindingFlags.Instance | System.Reflection.BindingFlags.InvokeMethod;

var uiApp = (Autodesk.Revit.UI.UIApplication)application.GetType().InvokeMember("getUIApplication", flag, Type.DefaultBinder, application, null);
