C # Background threads and foreground threads

The biggest difference between a background thread and a previous thread is that the background thread does not prevent the process from aborting, and when all foreground threads belonging to a process are aborted, the common language runtime ends the process, and all remaining background threads stop and do not complete.

The following is the demo code

using System; using System.Collections.Generic; using System.Text; using System.Threading; namespace ConsoleApplication1 {class Program {private static void Fntestthread (object data) {string sMsg; string sthreadname = Th Read. Currentthread.name; int nloopcount = (int) data; for (int i = 0; i < Nloopcount i++) {sMsg = string. Format ("Thread {0} Loop {1}", Sthreadname, I); Console.WriteLine (SMSG); Thread.Sleep (250); } SMSG = string. Format ("Thread {0} end", Sthreadname); Console.WriteLine (SMSG); static void Main (string[] args) {//foreground thread, performing 10 thread objforthread = new Thread (New Parameterizedthreadstart (Fntestthrea d)); Objforthread.name = "Foregroundthread"; Objforthread.start (20); Background thread, performing 50 thread objbackthread = new Thread (new Parameterizedthreadstart (Fntestthread)); Objbackthread.name = "Backgroundthread"; Objbackthread.isbackground = true; Objbackthread.start (50); } } }
