//模拟XNA的框架（凡是在wp7中应用xna的都必须先模拟此类） |
public
class XNAAsyncDispatcher : IApplicationService { private
DispatcherTimer frameworkDispatcherTimer; public
XNAAsyncDispatcher(TimeSpan dispatchInterval) { this.frameworkDispatcherTimer = new
DispatcherTimer(); this.frameworkDispatcherTimer.Tick += new
EventHandler(frameworkDispatcherTimer_Tick); this.frameworkDispatcherTimer.Interval = dispatchInterval; } void
IApplicationService.StartService(ApplicationServiceContext context) { this.frameworkDispatcherTimer.Start(); } void
IApplicationService.StopService() { this.frameworkDispatcherTimer.Stop(); } void
frameworkDispatcherTimer_Tick(object
sender, EventArgs e) { FrameworkDispatcher.Update(); } } |
在App 构造函数里写this.ApplicationLifetimeObjects.Add(new
XNAAsyncDispatcher(TimeSpan.FromMilliseconds(50)));当程序激动时就开始模拟XNA GameTimer |

本实例UI就两个Button 一个start 一个stop, 还有一个滑动条 Silder.
