How to check if Threads are done.

I implemented a for loop to request data for various assets:

String[] assets = new string[] { "Cc1", "Cc2", "ESc1", "ESc2" };
foreach(String s in assets)
{
	TimeSeriesRequest(s);
	Console.WriteLine("OK");
}

In the StopMessagePump() function I had to remove the Frame.Continue = false; statement because otherwise, the code would not complete for all 4 assets:

        public static void StopMessagePump()
        {
            //Frame.Continue = false;
            Console.WriteLine();
            Console.WriteLine("For other usage examples please uncomment the required method call in timeSeries_ServiceInformationChanged().");
            Console.WriteLine();
            Console.WriteLine("Press any key to exit...");
           // Console.ReadKey();
        }

However, to properly finish the program I must have Frame.Continue = false; somewhere after all async threads are finished. How can I check if all the loops are done?

    The API does not provide a counter for the instruments you request. Implementing your own counter as you did is indeed the best you can do. The reason why the API does not facilitate the instrument count is that implementing your own counter is simple enough and it serves a wider variety of use cases: you may want to have multiple lists of instruments and process them separately, for some instruments you may want to subscribe to streaming updates and for others you may not and so on.

    I kind of solved it by defining a global counter that keeps track of the # of assets you request and only goes to StopMessagePump() when it reaches the # of assets, but it's not very elegant..
    if (!chunk.IsLast)
    {
    	Console.WriteLine("NOT ISLAST " + chunk.Ric);
    	return;
    }
    else
    {
    	Console.WriteLine("ISLAST " + chunk.Ric + " " + Program.counter.ToString());
    	Program.counter++;
    	request = null;
    	if(Program.counter==4)
    		Program.StopMessagePump();
    }
