Help with C Sharp code

Question

Dear C Corner

I got a website with a search Box. If i want a program to run like 20 scripts or some word against that search box, what is the c code for such a program?

More simpel:

The hard way would be to type in

Hello
What
No
Yes
<script>doc.blablabla</script>
You

in the search box.

But i want the code for a program that does all that by itself.

Can you help me?
