于是今天我花了半天多的时间自己给封装了一个，（说明一下：在这种大热天没有空调的环境下，我竟然还感冒了，真是命苦啊 555）
控件有些不足的是 1 样式比较呆板，就支持如上图样式，因为这是基于一个Flash播放的，不是通过JS来控制的； 2 设计时的视图简单了点，目前就是让它只显示第一张图片，其实也够了，没必要搞多复杂，只要运行时效果好就行了，嘿嘿
看看主要代码把：
using System;using System.Collections.Generic;using System.Text;using System.Web.UI.WebControls;using System.ComponentModel;using System.Web.UI;using System.Drawing.Design;using System.Drawing;using System.Collections.ObjectModel;[assembly: WebResource(WebEX.RotatePictures.SWF, "application/x-shockwave-flash")]
namespace WebEX {
/// <summary>

}代码比较简单，这里主要把一个flash作为嵌入的资源了，以前从来没用过，现在感觉微软蛮强的哦 ：）
用法：
1 直接在设计时，添加图片
2 动态添加
protected void Button1_Click(object sender, EventArgs e) {
this.RotatePictures1.Pictures.Add(new WebEX.Picture("images/02.jpg", "baidu", "http://www.baidu.com"));
this.RotatePictures1.Pictures.Add(new WebEX.Picture("images/03.jpg", "163", "http://www.163.com"));
}
多多赐教，最后献上源码
