示例1: Main

using System;
using System.Threading;
class Example
{
static void Main()
{
BackgroundTest shortTest = new BackgroundTest(10);
Thread foregroundThread =
new Thread(new ThreadStart(shortTest.RunLoop));
BackgroundTest longTest = new BackgroundTest(50);
Thread backgroundThread =
new Thread(new ThreadStart(longTest.RunLoop));
backgroundThread.IsBackground = true;
foregroundThread.Start();
backgroundThread.Start();
}
}
class BackgroundTest
{
int maxIterations;
public BackgroundTest(int maxIterations)
{
this.maxIterations = maxIterations;
}
public void RunLoop()
{
for (int i = 0; i < maxIterations; i++) {
Console.WriteLine("{0} count: {1}",
Thread.CurrentThread.IsBackground ?
"Background Thread" : "Foreground Thread", i);
Thread.Sleep(250);
}
Console.WriteLine("{0} finished counting.",
Thread.CurrentThread.IsBackground ?
"Background Thread" : "Foreground Thread");
}
}输出：
Foreground Thread count: 0 Background Thread count: 0 Background Thread count: 1 Foreground Thread count: 1 Foreground Thread count: 2 Background Thread count: 2 Foreground Thread count: 3 Background Thread count: 3 Background Thread count: 4 Foreground Thread count: 4 Foreground Thread count: 5 Background Thread count: 5 Foreground Thread count: 6 Background Thread count: 6 Background Thread count: 7 Foreground Thread count: 7 Background Thread count: 8 Foreground Thread count: 8 Foreground Thread count: 9 Background Thread count: 9 Background Thread count: 10 Foreground Thread count: 10 Background Thread count: 11 Foreground Thread finished counting.
