What makes you thinking that "conversion" even makes sense? These programming technologies are very different. And you did not even explain what you want to achieve. It does not look a productive approach.

If you need to learn ASP.NET, try to do it, ask questions. And ultimately, implement what you need.

No.
We are not here to take your code, convert it (without knowing what it does, or is supposed to do), test it, debug it, and make it work.

In other words, do your work for you.

Try for yourself. If you get a specific problem, then feel free to come back and ask about it. But we will not do your whole task for you!
