Are there any common uses of C# do-while loop in web development? [closed]

Question

I've been coding for a long, long time, self-taught. Now that I'm working toward my computer science degree, my programming class is talking about post-test loops, the do-while loop.

Now I understand that it runs once, then checks the condition... since I'm a web programmer, I was wondering: what are some common web development (ASP.NET MVC/Razor preferably) scenarios where a do-while loop fits perfectly?

I'm not quite getting the concept straight in my mind...

Answer 1

I have been involved in many web projects and I can't remember for any specific use for this type of a loop. On web, you usually work just with collection of items and do some logic with each one of them. So I would say that most web developers just use foreach and for.

Do - While fits more into algorithms and calculations, and you don't do many of these in classic web development imo.

Answer 2

I don't know about MVC specifically, but a couple of years ago I had to create a administration page to enter data, on the client side you could add new fields to add staff member profiles. (name, title, education)

The controls were created client-side with JavaScript and numbered in sequence like:

txtStaffName0

txtStaffName1

txtStaffName2

Then used a do/while with the condition checking for the next incremented number for a control. Something along the lines of:

int count = 0;
do
{
   //find control with count and do stuff...
   count++;
} while (DoesControlExist(count));

Apart from that I don't think I've ever seen do/while used in web related stuff...
