我应该使用什么控件来显示保存在数据库中并编码为Image的图像

Question

All is in the question. I have an image saved in database in an Image column. How could i manage to display it in an aspx page ?

The problem is i don't know how to display an image without specifing an Url. Thanks in advance for your help Have a nice day

Answer 1

编写一个处理程序，该处理程序根据URL参数返回特定的图像（将图像的字节数组写入响应中）并将其设置为Image控件的URL。

Answer 2

Create a HTTP handler and called the handler in the in every img scr

<img src="ShowImg.ashx?ID=imageid" alt="imgetitle" />

handler will load the image from the imageid passed as a querystring to it. on handler we will right the code to read the image from database and display on the page.

Answer 3

You can do this with an HTTP Handler serving the image while referencing that handler in an html image tag.

Take a look at this article for an example.
