Encountering Issues Connecting to a Telegram Bot Using C#

I am facing a problem when attempting to connect my Telegram bot within a C# application. An error message arises, indicating an unhandled exception in the Windows Forms component. Specifically, it mentions a System.InvalidOperationException due to a cross-thread operation: a UI control is being modified by a thread that did not create it. I suspect this is causing the connection to fail. Below is a sample code snippet that mimics the connection scenario, though with different function names and variables:

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

public class BotManager : Form
{
    private Label statusLabel;

    public BotManager()
    {
        statusLabel = new Label();
        statusLabel.Text = "Starting Bot Connection...";
        this.Controls.Add(statusLabel);
    }

    public void InitializeBot()
    {
        Thread asyncThread = new Thread(new ThreadStart(UpdateStatus));
        asyncThread.Start();
    }

    private void UpdateStatus()
    {
        if (statusLabel.InvokeRequired)
        {
            this.Invoke(new Action(UpdateStatus));
        }
        else
        {
            statusLabel.Text = "Bot Connected Successfully";
        }
    }

    [STAThread]
    public static void Main()
    {
        Application.Run(new BotManager());
    }
}

I would appreciate any insights into mitigating this threading issue to ensure a smooth connection process.

During a previous project, I encountered a similar issue where updating the device information from a background thread led to a cross-thread operation exception. I solved this by ensuring that any code responsible for updating UI components was encapsulated within a delegate and safely invoked using the Invoke method on the control, similarly to what you already have. I also considered using asynchronous patterns like async/await to simplify the UI update process, which helped improve code clarity and reduce threading issues. Experimenting with these methods often leads to a more stable application.
