C# - How To Repeat HTML Parts With Minor Differences On A Page

I've got HTML code like this :

<div>
<img src="image1.jpg" alt="test1" />
</div>
<div>
<img src="image2.jpg" alt="test2" />
</div>
<div>
<img src="image3.jpg" alt="test3" />
</div>

The data is comming from a DB (image name, alt text).

In JAVA, I would do something like :

save the info in array in the back end.

For the presentation I would loop through it with JSTL :

<c:foeach items="${data}" var="${item}>
<div>
<img src="${item.image}" alt="${item.alt}" />
</div>
</c:foreach>

What's the best practice in ASP.net I just don't want to create a string with HTML code in it in the "code behind",
