推荐答案

ASP.NET AJAX库具有幻灯片放映控件.您的另一个问题是创建一个页面，该页面根据id返回数据库中每个图像的字节，但是Web上有大量的示例.

The ASP.NET AJAX library has a slideshow control. Your other issue will be to create a page that returns the bytes of each image from you DB based on an id, but there''s tons of samples on the web for that.

为什么不要为图像创建

HttpHandler 

.只需将图像文件字节从数据库中放入，然后将其写入响应流即可.

在客户端放置一个javascript，它将使用setInterval("changeImage()", 1000)
逐个调用图像
在您的函数changeImage()中放入调用Handler的适当路径.

通过JavaScript修改document.getElementById(Img).src时，系统会自动调用您的图片.

for the images. Just put the image file bytes from the database and write it to response stream.

From the client side place a javascript which will call the images one by one using setInterval("changeImage()", 1000)

Inside your function changeImage() put appropriate path which invokes the Handler.

Your Image will be called automatically when document.getElementById(Img).src is modified through javascript.
