Synchronizing events from different threads in console application

You could try a BlockingCollection

BlockingCollection<Action> actions = new BlockingCollection<Action>();void main() {   // start your tasks   while (true) {       var action = actions.Take();       action();   }}static void t_First(object sender, EventArgs e) {    string message = "- first callback on:" + Thread.CurrentThread.ManagedThreadId;    actions.Add(_ => Console.WriteLine(message));}

If I understand you right, you are asking about how to execute code running on thread into different thread. i.e: you have two threads, while you are executing the second thread code you want to execute it in the first thread.

You can achieve this by using SynchronizationContext, for example if you want to execute code from another thread into main thread, you should use current synchronization context:

private readonly System.Threading.SynchronizationContext _currentContext = System.Threading.SynchronizationContext.Current;private readonly object _invokeLocker = new object();public object Invoke(Delegate method, object[] args){    if (method == null)    {        throw new ArgumentNullException("method");    }    lock (_invokeLocker)    {        object objectToGet = null;        SendOrPostCallback invoker = new SendOrPostCallback(        delegate(object data)        {            objectToGet = method.DynamicInvoke(args);        });        _currentContext.Send(new SendOrPostCallback(invoker), method.Target);        return objectToGet;     }}

While you are in the second thread, using this method will execute code on the main thread.

you can implement ISynchronizeInvoke "System.ComponentModel.ISynchronizeInvoke". check this example.

Edit: Because of you are running a Console application and so can't use SynchronizationContext.Current. then you probably need to design your own SynchronizationContext, this example might help.
