如何在 C# 中检查线程是否为后台线程


要检查线程是否为后台线程,代码如下:

示例

 实时演示

using System;
using System.Threading;
public class Demo {
   public static void Main() {
      Thread thread = new Thread(new ThreadStart(demo1));
      ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
      Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);
      Console.WriteLine("Is the Thread a background thread? = "+Thread.CurrentThread.IsBackground);
   }
   public static void demo1() {
      Thread.Sleep(2000);
   }
   public static void demo2(object stateInfo) {
      Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

输出

这将产生以下输出:

Current state of Thread = Unstarted
ManagedThreadId = 721
Is the Thread a background thread? = False
Thread belongs to managed thread pool? = True

示例

让我们看另一个示例:

 实时演示

using System;
using System.Threading;
public class Demo {
   public static void Main() {
      Thread thread = new Thread(new ThreadStart(demo1));
      ThreadPool.QueueUserWorkItem(new WaitCallback(demo2));
      Console.WriteLine("Current state of Thread = "+thread.ThreadState);
      Console.WriteLine("ManagedThreadId = "+thread.ManagedThreadId);
      thread.IsBackground = true;
      Console.WriteLine("Is the Thread a background thread? = "+thread.IsBackground);
   }
   public static void demo1() {
      Thread.Sleep(2000);
   }
   public static void demo2(object stateInfo) {
      Console.WriteLine("Thread belongs to managed thread pool? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

输出

这将产生以下输出:

Current state of Thread = Unstarted
ManagedThreadId = 1114
Is the Thread a background thread? = True
Thread belongs to managed thread pool? = True
