using System.Threading;
using System.Windows.Forms;
public partial class Form1 : Form
{
    private Thread printThread;
    private ManualResetEvent pauseEvent = new ManualResetEvent(true);
    public Form1()
    {
        InitializeComponent();
        printThread = new Thread(new ThreadStart(PrintValues));
        printThread.Start();
    }
    private void btnStart_Click(object sender, EventArgs e)
    {
        pauseEvent.Set();
    }
    private void btnPause_Click(object sender, EventArgs e)
    {
        pauseEvent.Reset();
    }
    private void PrintValues()
    {
        int i = 0;
        while (true)
        {
            pauseEvent.WaitOne();
            Debug.WriteLine(i);
            i++;
