freeze winform app until loop exits

I have an app running and when a specific button is hit it runs a bunch of tasks. I want to freeze the tasks at one point until a loop is finished. Not sure why this code isn't doing that:

loop = true;

    //loop while receiving data to prevent going past this point until the end
    while (loop == true)
    {
        //upon data receipt from tracer, send data to dataReceivedHandler function
        port.DataReceived += new SerialDataReceivedEventHandler(dataRecievedHandler);
    }

loop = true;

    //loop while receiving data to prevent going past this point until the end
    while (loop == true)
    {
        //upon data receipt from tracer, send data to dataReceivedHandler function
        port.DataReceived += new SerialDataReceivedEventHandler(dataRecievedHandler);
    }

Later in the code I have a loop=false in my dataReceivedHandlerFuntion to break the loop but code after this code is executing prematurely

that is a huge memory leak you're subscribing additional handlers to the event as fast as possible in an infinite loop

okay well then I will not do it this way my goal is to loop on receiving data until complete and then move on

if you want code in one thread to wait until code in another thread is done, use a reset event or semaphore or tasks with async/await

that should be enough for me to lookup what you mean I think thank you
