我正在构建类似facebook的模型。所以我想从数据库中检索相关数据并插入到这个HTML元素中以显示它。但现在我面临的问题是我只能显示其中一条记录。我想要做的是使用foreach循环来循环用户＆＃39;根据我在数据库中记录的数量发布帖子。无论如何，我可以将HTML代码添加到C＃文件的foreach循环中以实现所需的效果吗？谢谢。

有几种方法可以做到这一点。基本上你需要包装你的＆＃34; userPost＆＃34;转发器中的div类似于＆＃34;列表视图＆＃34;。＆＃34; userPost＆＃34;将是listview中的itemTemplate。看看这个enter link description here
