C# TCP client - Performing transfer on all forms without interruption?

Question

.NET

Good day to all, I have a server on tcp and a client with several WinForms. What can be done to call Connect on 1 form, and on the next ones, only pass the values ​​​​for sending.
1. Form 1 - Connect
2. Send/receive byte array (Form 1)
3. Transition to Form 2
4. Send/receive byte array (Form 2)
5. Transition to Form 3
6. Send/receive byte array (Form 2 )
As a result, you need 1 Connect on 1 form, and then only receive and transmit data. Interruption of communication between the client and the server during the transition between forms is not allowed.
My actions:
1. Thread, Task - can only be called by 1 form, when switching to another form, the thread ends (it almost didn’t work out with it)
2. OOP - created a separate class for connections, connect, receive, etc. I call on the form 1 connect and transfer the array, then I go to the form, I start transferring the byte array and the error requires connect i.e. the connection was terminated.
Where to dig, tell me what to use?

Answer 1

We created a class for the connection, and then, when creating new forms, pass its instance through the parameters of the form constructor.
