how do i start many threads in a queue?
private void Paste()
{
    foreach (ListViewItem item in copiedItems)
    {
        Thread pasteC = new Thread(unused => fmc.PasteFromCopy(item.Text, somePath));
        pasteC.Start();
    }
}

public void PasteFromCopy(string source,string dest)
{
    if (IsFolder(source))
    {
        CopyDirectory(source, dest);
    }
    else
    {
        CopyStream(source, dest);
    }
}

private void Paste()
{
    foreach (ListViewItem item in copiedItems)
    {
        fmc.PasteFromCopy(item.Text, somePath);
    }
}

private void Paste()
{
    var thread = new Thread(() =>
    {
        foreach (ListViewItem item in copiedItems)
        {
            fmc.PasteFromCopy(item.Text, somePath);
        }
    });
    thread.Start();
}

public void PasteFromCopy(string source,string dest)
{
    lock(this)
    {
        if (IsFolder(source))
        {
            CopyDirectory(source, dest);
        }
        else
        {
            CopyStream(source, dest);

        }
    }
}

object _sync;
ManualResetEvent _start;
Queue<KeyValuePair<string, string>> _copyQueue;

private void Paste()
{
    foreach (ListViewItem item in copiedItems)
        _copyQueue.Enqueue(new KeyValuePair<string, string>(item.text, somepath));
}

void Thread()
{
   start.Wait();
   while(_copyQueue.Count > 0)
   {
      lock(_sync)
      {
          if(_copyQueue.Count == 0)
             break;
           new Task(PasteFromCopy(_copyQueue.Dequeue()));
      }
   }
}
