自定义WebControl:广告控件
花3小时写了个广告控件
组合了3中广告形式：1，Flash的轮显广告，如zol.com.cn笔记本频道首页广告。2，一般的flash广告。3，一般的图片广告。
代码如下：
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Text;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
namespace AppControl
{
[ToolboxData("<{0}:Advertisement runat=server></{0}:Advertisement>")]
public class Advertisement : WebControl
{
protected override void RenderContents(HtmlTextWriter output)
{
output.Write(AdCode);
}
#region 属性

[Description("广告代码")]
public string AdCode
{
get
{
StringBuilder sb = new StringBuilder();
switch (AdType)
{
case AdTypeList.Img:
sb.AppendFormat(@"<a href='{0}' target='_blank'><img src='{1}' width='{2}' height='{3}' border='0' alt='{4}' title='{5}'", Links, Pics, Width, Height, Texts, Texts);
if (CssClass != null)
{
sb.AppendFormat(@" class={0}", CssClass);
}
sb.AppendFormat(@"/></a>");
break;
case AdTypeList.Flash:
sb.AppendFormat(@"<div");
if (CssClass != null)
{
sb.AppendFormat(" class='{0}'", CssClass);
}
sb.AppendFormat(@"><object classid='clsid:D27CDB6E-AE6D-11cf-96B8-444553540000' width='{0}' height='{1}'>

break;

if (CssClass != null)
