flash player是以一个com+组件的形式插入到C#应用程序中的. 加入的方法和普通com+控件一样.这是我今年2月做的一个小试验。事实上我上半年做的项目一直跟这方面有关，所以对这方面还是有一些经验的。现在由于公司项目的启动，所以要对这个熟悉一下，然后整以成熟的方法，使它们之间的接口更有通用性。这方面有一个开源项目flashCsharp做得还不错。但他只是对文件控制不错，扩展性不是很强。这个小试验是一个媒体播放器，由flash来控制，先熟悉一下。

this.axShockwaveFlash1.FSCommand += new AxShockwaveFlashObjects._IShockwaveFlashEvents_FSCommandEventHandler(this.axShockwaveFlash1_FSCommand);而C#中也可以向flash设置参数，如:string flashData = "一二三四五六七"; axShockwaveFlash1.SetVariable("data",flashData);这样的话可以在flash中通过Obejct.watch()得到变化。
