How to send a Post request using C# for a given page?

Question

C++ / C#

I am writing a small application for myself to find out when I have English classes.
Here is the login page .
The login page seems to be simple. You need to fill in a username, password and select a school.
How can I do this using C#?
I'm practically zero on the web.
As far as I understand, you need to use the WebClient class in C#.
