不知道哪位高手知道执行这个页面下的兑换是执行了什么函数阿？我想写个c#程序一直执行这个兑换，人工点不够快被抢光了。
我用invokemember("click")但是没用，分析数据包麻烦，想问问怎么用c#来写模拟点击兑换按钮的程序

以下是与IE浏览器通信的类,调用系统API,查找窗口,获取IHTMLDocument对象(相当于网页中的document对象),其它操作可通过javascript实现. 添加MSHTML引用

你用 WebBrowser
HtmlDocument hb = wb.Document;
hb.GetElementById();//得到那个按钮然后写事件
处理一下点击，当然还要显示出验证码,手工填写.
