How to write a C# program to send a request to a server via SSH?

Question

SSH

Good day. I recently began to study programming in C # for my self-development, so to speak.
There was a question. There is a server with ubuntu - privoxy - tor installed on it. Since tor is not always needed, I would like to implement the ability to turn it off on a click without going to the server. There was an idea to implement an application with access via SSH, but I could not find how to correctly write the code to enter the server, enter the password and further commands.

If anyone can share where to look or what method to use.
Thank you very much in advance!
