Thread.IsThreadPoolThread 属性
定义
重要
一些信息与预发行产品相关,相应产品在发行之前可能会进行重大修改。 对于此处提供的信息,Microsoft 不作任何明示或暗示的担保。
获取一个值,该值指示线程是否属于托管线程池。
public:
property bool IsThreadPoolThread { bool get(); };
public bool IsThreadPoolThread { get; }
member this.IsThreadPoolThread : bool
Public ReadOnly Property IsThreadPoolThread As Boolean
属性值
true 如果此线程属于托管线程池,则为 ;否则,为 false.
示例
下面的代码示例演示如何确定线程是否来自线程池。
using System;
using System.Threading;
class IsThreadPool
{
static void Main()
{
AutoResetEvent autoEvent = new AutoResetEvent(false);
Thread regularThread =
new Thread(new ThreadStart(ThreadMethod));
regularThread.Start();
ThreadPool.QueueUserWorkItem(new WaitCallback(WorkMethod),
autoEvent);
// Wait for foreground thread to end.
regularThread.Join();
// Wait for background thread to end.
autoEvent.WaitOne();
}
static void ThreadMethod()
{
Console.WriteLine("ThreadOne, executing ThreadMethod, " +
"is {0}from the thread pool.",
Thread.CurrentThread.IsThreadPoolThread ? "" : "not ");
}
static void WorkMethod(object stateInfo)
{
Console.WriteLine("ThreadTwo, executing WorkMethod, " +
"is {0}from the thread pool.",
Thread.CurrentThread.IsThreadPoolThread ? "" : "not ");
// Signal that this thread is finished.
((AutoResetEvent)stateInfo).Set();
}
}
open System.Threading
let threadMethod () =
printfn
$"""ThreadOne, executing ThreadMethod, is {if Thread.CurrentThread.IsThreadPoolThread then
""
else
"not "}from the thread pool."""
let workMethod stateInfo =
printfn
$"""ThreadTwo, executing WorkMethod, is {if Thread.CurrentThread.IsThreadPoolThread then
""
else
"not "}from the thread pool."""
// Signal that this thread is finished.
(unbox<AutoResetEvent> stateInfo).Set() |> ignore
let autoEvent = new AutoResetEvent false
let regularThread = Thread threadMethod
regularThread.Start()
ThreadPool.QueueUserWorkItem(workMethod, autoEvent) |> ignore
// Wait for foreground thread to end.
regularThread.Join()
// Wait for background thread to end.
autoEvent.WaitOne() |> ignore
