动态绑定Flash的图片和标题-优快云博客

该博客介绍了一个使用Flash技术显示新闻文章中图片的方法。通过解析新闻内容获取图片链接，并将其与标题一起用于生成Flash幻灯片。代码实现了从文章列表中提取最多五篇文章的首张图片及其标题，最终以Flash组件形式在页面上展示。

public void showFlash()
{
IList<NewsArticle> articleList = article.ListNewsArticleByRows("22",500);

        int count = 0;

        string texts = "";

        {
            NewsArticle articleNew = (NewsArticle)articleList[i];
            if (articleNew.Content == "")
            {
                continue;
            }
