1.main函数：

    class Program
    {
        static void Main(string[] args)
        {
            log4net.Config.XmlConfigurator.Configure();
            ConsoleOutput.ConsoleEnabled = true;
            ConsoleRun();
        }

        private static void ConsoleRun()
        {
            string title = ConfigurationManager.AppSettings["ProgramTitle"];
            Console.Title = title;
            Console.WriteLine(title);
            Console.WriteLine();
            ConsoleOutput.ShowInfomationLine(title + "程序开始");

            var backgroudWorker = new BackgroundWorker { WorkerSupportsCancellation = true };
            backgroudWorker.DoWork += (sender, e) =>
            {
                var backgroundWorker = (BackgroundWorker)sender;
                NoticeWorker.Deamon(backgroundWorker);
            };
            backgroudWorker.RunWorkerAsync();

            Console.ReadLine();

            Console.Title = title + "消息队列 -- 正在停止 ... ";
            backgroudWorker.CancelAsync();

            Console.WriteLine(@"
 **************************************** 
 *                                      * 
 *  服务已停止。请按回车键关闭此窗口。  * 
 *                                      * 
 **************************************** 
");
            Console.Title = title + "消息队列 -- 已停止";
            Console.ReadLine();
        }
    }

2.NoticeWorker类

public class NoticeWorker
{
	public static void Deamon(BackgroundWorker backgroundWorker)
	{
		while (!backgroundWorker.CancellationPending)
		{
			try
			{
				//do job
			}
			catch (Exception ex)
			{
				 _logger.Error("程序出错", ex);
			}
		}
	}
}
