Is there anyway to make this piece of code more elegant? Cause, it´s not a nice view, but i can´t really see a way to Improve the looks of it, or shorten it.

But hopefully there is.

EDIT:

I am trying to find a nice way to put TCP reconnecting in another class, but i find a limitation where i have to call return, on the main class.

Here:

So, when it´s failing, it goes out of the loop. I can also make it call Return, but it will do the same thing.

In the Class Caller i have to use:

 FastMethods.TCPReconnect(CTS, tcp, adress);
                    if (CTS.IsCancellationRequested)
                        return;

So as you can see, i have to recheck for CTS. Is it possible to have it inside the other Class somehow?

Cause if i use

            if (CTS.IsCancellationRequested)
                return;

Is there anyway to make this piece of code more elegant? It's not a nice view, but I can't really see a way to improve the looks of it or shorten it.

I am trying to find a nice way to put TCP reconnecting in another class, but I found a limitation where I have to call return in the main class.

Here:

internal static void TCPReconnect(CancellationToken CTS, TcpClient tcp, IPEndPoint adress)
{
    tcp.NoDelay = true;
    while (!tcp.Connected && !CTS.IsCancellationRequested)
    {
        try
        {
            if (!tcp.Connected)
                tcp.Connect(adress);

            else
                MessageBox.Show(e.Message + " Tcp Connect : Send");

So as you can see, i have to recheck for CTS. Is it possible to have it inside the other Class somehow?

Cause if i use

            if (CTS.IsCancellationRequested)
                return;

It will simply return to the main class and continue.
