C# Thread Queue Synchronize

Greetings, I am trying to play some audio files without holding up the GUI. Below is a sample of the code:

if (audio)
{
    if (ThreadPool.QueueUserWorkItem(new WaitCallback(CoordinateProc), fireResult))
    {

    }
    else
    {
        MessageBox.Show("false");
    }
}

if (audio)
{
    if (ThreadPool.QueueUserWorkItem(new WaitCallback(FireProc), fireResult))
    {

    }
    else
    {
         MessageBox.Show("false");
    }
}

if (audio)
{
    if (ThreadPool.QueueUserWorkItem(new WaitCallback(HitProc), fireResult))
    {

    }
    else
    {
        MessageBox.Show("false");
    }
}

The situation is the samples are not being played in order. some play before the other and I need to fix this so the samples are played one after another in order.

How do I implement this please?

Thank you.

EDIT: ThreadPool.QueueUserWorkItem(new WaitCallback(FireAttackProc), fireResult);

I have placed all my sound clips in FireAttackProc. What this does not do and I want is: wait until the thread stops running before starting a new thread so the samples dont overlap.

Solution

  • Why not just create one "WorkItem" and do everything there?
