Try this. The function takes in a list of Action delegates. It will add a ThreadPool worker entry for each item in the list. It will wait for every action to complete before returning.
public static void SpawnAndWait(IEnumerable<Action> actions)
{
var list = actions.ToList();
var handles = new ManualResetEvent[actions.Count()];
for (var i = 0; i < list.Count; i++)
{
handles[i] = new ManualResetEvent(false);
var currentAction = list[i];
var currentHandle = handles[i];
Action wrappedAction = () => { try { currentAction(); } finally { currentHandle.Set(); } };
ThreadPool.QueueUserWorkItem(x => wrappedAction());
}
WaitHandle.WaitAll(handles);
}
