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
