namespace CanData02
{
public class Program
{
static void Main(string[] args)
{
int handle;
Canlib.canStatus status;
int channelNumber = 0;

Canlib.canInitializeLibrary();

handle = Canlib.canOpenChannel(channelNumber, Canlib.canOPEN_ACCEPT_VIRTUAL);
CheckStatus((Canlib.canStatus)handle, "canOpenChannel");

status = Canlib.canSetBusParams(handle, Canlib.canBITRATE_250K, 0, 0, 0, 0, 0);
CheckStatus(status, "canSetBusParams");

status = Canlib.canBusOn(handle);
CheckStatus(status, "canBusOn");

DumpMessageLoop(handle);
}
private static void DumpMessageLoop(int handle)
{
Canlib.canStatus status;
bool finished = false;
byte[] data = new byte[8];
int id;
int dlc;
int flags;
long timestamp;

Console.WriteLine("Channel opened. Press Escape to close. ");
Console.WriteLine("ID DLC DATA Timestamp");

while (!finished)
{
status = Canlib.canReadWait(handle, out id, data, out dlc, out flags, out timestamp, 100);

if (status == Canlib.canStatus.canOK)
{
DumpMessage(id, data, dlc, flags, timestamp);
}
else if (status != Canlib.canStatus.canERR_NOMSG)
{
CheckStatus(status, "canReadWait");
finished = true;
}
}
}
private static void DumpMessage(int id, byte[] data, int dlc, int flags, long timestamp)
{
if ((flags & Canlib.canMSG_ERROR_FRAME) != 0)
{
Console.WriteLine("Error Frame received ****");
}
else
{
Console.WriteLine($"{id} {dlc} {data[0]:x2} {data[1]:x2} {data[2]:x2} {data[3]:x2} {data[4]:x2} {data[5]:x2} {data[6]:x2} {data[7]:x2} {timestamp}");
}
}
private static void CheckStatus(Canlib.canStatus status, string method)
{
if (status < 0)
{
Console.WriteLine($"{method} failed: {status.ToString()}");
}
}
}
}

Accepted answer
For Windows Forms the BackgroundWorker class is designed for this type of use. Your DumpMessageLoop would be the BackgroundWorker.DoWork event. The DoWork event executes as a different thread. The output to the window could be sent to the window using the ProgressChanged event and the BackgroundWorker class will provide the switching to the UI thread. The documentation provides many examples and there are many relevant articles. Let us know if you have specific questions.

Check Below Refrence code , and change it according to your requirement

using System;
using System.IO;
using System.Threading;
using System.Windows.Forms;

namespace YourNamespace
{
    public partial class MainForm : Form
    {
        private Thread consoleThread;
        private TextWriter originalConsoleOutput;

        public MainForm()
        {
            InitializeComponent();
            originalConsoleOutput = Console.Out;
            consoleThread = new Thread(new ThreadStart(StartConsole));
        }

        private void StartConsole()
        {
            using (StringWriter stringWriter = new StringWriter())
            {
                Console.SetOut(stringWriter);

                // Your existing console application logic goes here
                // For the purpose of example, let's simulate continuous data updates
                for (int i = 0; i < 10; i++)
                {
                    Console.WriteLine($"Data: {i}");
                    Thread.Sleep(1000); // Simulating continuous data every second
                }
                
                // Retrieve the console output
                string consoleOutput = stringWriter.ToString();

                // Update the RichTextBox on the UI thread
                this.Invoke((MethodInvoker)delegate
                {
                    richTextBox1.AppendText(consoleOutput);
                });
            }
        }

        private void btnStart_Click(object sender, EventArgs e)
        {
            // Start the thread when the button is clicked
            consoleThread.Start();
        }

        private void MainForm_FormClosing(object sender, FormClosingEventArgs e)
        {
            // Restore the original Console.Out before closing the form
            Console.SetOut(originalConsoleOutput);
        }
    }
}
