Process queue with multithreading or tasks

Question

I have a telephony message application in which there are many many messages to be processed.Because telephone ports are limited, so the message will be processed first in f

Answer 1

Parallel.ForEach from TPL. It's parallel for-each.

Sample (changed MessageWorkItem to generic Queue):

    public class MessageQueue
{
    public Queue MessageWorkItem { get; set; }

    public MessageQueue()
    {
        MessageWorkItem = new Queue();
    }

    public Message GetMessageMetaData()
    {
        try
        {
            // It is just a test, add only one item into the queue
            return new Message()
            {
                MessageID = Guid.NewGuid(),
                NumberToCall = "1111111111",
                FacilityID = "3333",
                NumberToDial = "2222222222",
                CountryCode = "1",
                Acknowledge = false
            };
        }
        catch (Exception ex)
        {
            return null;
        }
    }

    public void AddingItemToQueue()
    {
        var message = GetMessageMetaData();
        if (!message.Acknowledge)
        {
            lock (MessageWorkItem)
            {
                MessageWorkItem.Enqueue(message);
            }
        }
    }
}

public class Message
{
    public Guid MessageID { get; set; }
    public string NumberToCall { get; set; }
    public string FacilityID { get; set; }
    public string NumberToDial { get; set; }
    public string CountryCode { get; set; }
    public bool Acknowledge { get; set; }
}

class Program
{
    static void Main(string[] args)
    {
        MessageQueue me = new MessageQueue();
        for (int i = 0; i < 10000; i++)
            me.AddingItemToQueue();

        Console.WriteLine(me.MessageWorkItem.Count);

        Parallel.ForEach(me.MessageWorkItem, RunScript);
    }

    static void RunScript(Message item)
    {
        // todo: ...
        Console.WriteLine(item.MessageID);
        Thread.Sleep(300);
    }
}
