Thread.ThreadState Свойство
Определение
Важно!
Некоторые сведения относятся к предварительной версии продукта, в которую до выпуска могут быть внесены существенные изменения. Майкрософт не предоставляет никаких гарантий, явных или подразумеваемых, относительно приведенных здесь сведений.
Возвращает значение, содержащее состояния текущего потока.
public:
property System::Threading::ThreadState ThreadState { System::Threading::ThreadState get(); };
public System.Threading.ThreadState ThreadState { get; }
member this.ThreadState : System.Threading.ThreadState
Public ReadOnly Property ThreadState As ThreadState
Значение свойства
Одно из значений ThreadState, показывающее состояние текущего потока. Начальное значение — Unstarted.
Примеры
В следующем примере кода демонстрируется ThreadState
доступ к потоку.
using namespace System;
using namespace System::Threading;
// ref class ApartmentTest
// {
// public:
static void ThreadMethod()
{
Thread::Sleep( 1000 );
// }
};
int main()
{
// Thread^ newThread = gcnew Thread( gcnew ThreadStart( &ApartmentTest::ThreadMethod ) );
Thread^ newThread = gcnew Thread( gcnew ThreadStart( &ThreadMethod ) );
Console::WriteLine("ThreadState: {0}", newThread->ThreadState);
newThread->Start();
// Wait for newThread to start and go to sleep.
Thread::Sleep(300);
Console::WriteLine("ThreadState: {0}", newThread->ThreadState);
// Wait for newThread to restart.
Thread::Sleep(1000);
Console::WriteLine("ThreadState: {0}", newThread->ThreadState);
}
// The example displays the following output:
// ThreadState: Unstarted
// ThreadState: WaitSleepJoin
// ThreadState: Stopped
using System;
using System.Threading;
class Example
{
static void Main()
{
Thread newThread =
new Thread(new ThreadStart(ThreadMethod));
Console.WriteLine("ThreadState: {0}", newThread.ThreadState);
newThread.Start();
// Wait for newThread to start and go to sleep.
Thread.Sleep(300);
Console.WriteLine("ThreadState: {0}", newThread.ThreadState);
// Wait for newThread to restart.
Thread.Sleep(1000);
Console.WriteLine("ThreadState: {0}", newThread.ThreadState);
}
static void ThreadMethod()
{
Thread.Sleep(1000);
}
}
// The example displays the following output:
// ThreadState: Unstarted
// ThreadState: WaitSleepJoin
// ThreadState: Stopped

Thread.Sleep 300
printfn $"ThreadState: {newThread.ThreadState}"
// Wait for newThread to restart.

// The example displays the following output:

Комментарии
Свойство ThreadState предоставляет более конкретные сведения, чем IsAlive свойство .
Важно!
Состояние потока представляет интерес только для сценариев отладки. Не используйте в коде состояния потоков для синхронизации действий потоков.
