use server and client to send data and use these data to do something between unity and my c# project

1. I already have the client and server scripts for my project, but face some problems that need to write a new script or help me to change the code.
2. need to use the google remote desktop to finish the project because I can't give the file to you, and also need to use google Meetings to discuss with me because I can tell you where my problem is.
