Thread.ThreadState Vlastnost

Definice

Získá hodnotu obsahující stavy aktuálního vlákna.Gets a value containing the states of the current thread.

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

Hodnota vlastnosti

Jedna z hodnot ThreadState označující stav aktuálního vlákna.One of the ThreadState values indicating the state of the current thread. Počáteční hodnota je Unstarted.The initial value is Unstarted.

Příklady

Následující příklad kódu ukazuje přístup k ThreadState vlákna.The following code example demonstrates accessing the ThreadState of a thread.

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
Imports System.Threading

Public Module Example
    Public Sub Main()
        Dim newThread As Thread = New Thread(AddressOf 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)
    End Sub

    Sub ThreadMethod()
        Thread.Sleep(1000)
    End Sub
End Module
' The example displays the following output:
'       ThreadState: Unstarted
'       ThreadState: WaitSleepJoin
'       ThreadState: Stopped

Poznámky

Vlastnost ThreadState poskytuje konkrétnější informace než vlastnost IsAlive.The ThreadState property provides more specific information than the IsAlive property.

Důležité

Stav vlákna je pouze v zájmu ve scénářích ladění.Thread state is only of interest in debugging scenarios. Váš kód by nikdy neměl používat stav vlákna k synchronizaci aktivit vláken.Your code should never use thread state to synchronize the activities of threads.
