Here some code:

private void cmdStart Click(object sender, System.EventArgs e)
{
// Let's create a new thread
primeNumberThread = new Thread(
new ThreadStart(GeneratePrimeNumbers));

// Let's give a name for the thread
primeNumberThread.Name = "Prime Numbers Example";

primeNumberThread.Priority = ThreadPriority.BelowNormal;

// Enable the Pause Button
cmdPause.Enabled = true;
// Disable the Start button
cmdStart.Enabled = false;

// Let's start the thread
primeNumberThread.Start();
}

private void cmdPause Click(object sender, System.EventArgs e)
{
try
{
try
{
// If current state of thread is Running,
// then pause the Thread
if (primeNumberThread.ThreadState ==
System.Threading.ThreadState.Running)
{

//Pause the Thread
primeNumberThread.Suspend();

//Disable the Pause button
cmdPause.Enabled = false;

//Enable the resume button
cmdResume.Enabled = true;
}
}
catch(ThreadStateException Ex)
{
MessageBox.Show(Ex.ToString(), "Exception",
MessageBoxButtons.OK, MessageBoxIcon.Error,
MessageBoxDefaultButton.Button1);
}
}
private void cmdResume Click(object sender, System.EventArgs e)
{
if(primeNumberThread.ThreadState ==
System.Threading.ThreadState.Suspended ||
primeNumberThread.ThreadState ==
System.Threading.ThreadState.SuspendRequested)
{
try
{
// Resume the thread
primeNumberThread.Resume();

// Disable the resume button
cmdResume.Enabled = false;

// Enable the Pause button
cmdPause.Enabled = true;
}
catch(ThreadStateException Ex)
{
MessageBox.Show(Ex.ToString(), "Exception",
MessageBoxButtons.OK, MessageBoxIcon.Error,
MessageBoxDefaultButton.Button1);
}
}
}
public void GeneratePrimeNumbers()
{
long lngCounter;
long lngNumber;
long lngDivideByCounter;
bool blnIsPrime;
long[] PrimeArray = new long[256];

// initialize variables
lngNumber = 3;
lngCounter = 2;

// We know that the first prime is 2. Therefore,
// let's add it to the list and start from 3
PrimeArray[1] = 2;
lstPrime.Items.Add(2);

while(lngCounter < 256)
{
blnIsPrime = true;

lngCounter++;

// Let's put the thread to sleep for 100 milliseconds.
// This will simulate the time lag and we'll get time
// to pause and resume the thread
Thread.Sleep(100);
}

// Increment number by two
lngNumber += 2;
}
// Once the thread is finished execution enable the start
// and di
