如何在C#中检查线程是否为后台线程

要检查线程是否是后台线程，代码如下：

示例

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("线程是后台线程吗? = "+Thread.CurrentThread.IsBackground);
   }
   public static void demo1() {
      Thread.Sleep(2000);
   }
   public static void demo2(object stateInfo) {
      Console.WriteLine("线程属于托管线程池? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

输出结果

这将产生以下输出-

Current state of Thread = Unstarted
ManagedThreadId = 721
线程是后台线程吗? = False
线程属于托管线程池? = True

示例

让我们看另一个例子-

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("线程是后台线程吗? = "+thread.IsBackground);
   }
   public static void demo1() {
      Thread.Sleep(2000);
   }
   public static void demo2(object stateInfo) {
      Console.WriteLine("线程属于托管线程池? = "+Thread.CurrentThread.IsThreadPoolThread);
   }
}

输出结果

这将产生以下输出-

Current state of Thread = Unstarted
ManagedThreadId = 1114
线程是后台线程吗? = True
线程属于托管线程池? = True
