Question

Which is the best timer approach for a C# console batch application that has to process as follows:

1. Connect to datasources
2. process batch until timeout occurs or processing complete. ‘Do something with datasources’
3. stop console app gracefully.

Sorry for this being an entire console app… but here’s a complete console app that will get you started. Again, I appologize for so much code, but everyone else seems to be giving a ‘oh, all you have to do is do it’ answer 🙂

using System; using System.Collections.Generic; using System.Threading;  namespace ConsoleApplication1 {     class Program     {         static List<RunningProcess> runningProcesses = new List<RunningProcess>();          static void Main(string[] args)         {             Console.WriteLine('Starting...');              for (int i = 0; i < 100; i++)             {                 DoSomethingOrTimeOut(30);             }              bool isSomethingRunning = false;              do             {                 foreach (RunningProcess proc in runningProcesses)                 {                     // If this process is running...                     if (proc.ProcessThread.ThreadState == ThreadState.Running)                     {                         isSomethingRunning = true;                          // see if it needs to timeout...                         if (DateTime.Now.Subtract(proc.StartTime).TotalSeconds > proc.TimeOutInSeconds)                         {                             proc.ProcessThread.Abort();                         }                     }                 }             }             while (isSomethingRunning);              Console.WriteLine('Done!');                  Console.ReadLine();         }          static void DoSomethingOrTimeOut(int timeout)         {             runningProcesses.Add(new RunningProcess             {                 StartTime = DateTime.Now,                 TimeOutInSeconds = timeout,                 ProcessThread = new Thread(new ThreadStart(delegate                   {                       // do task here...                   })),             });              runningProcesses[runningProcesses.Count - 1].ProcessThread.Start();         }     }      class RunningProcess     {         public int TimeOutInSeconds { get; set; }          public DateTime StartTime { get; set; }          public Thread ProcessThread { get; set; }     } }
