Thread.ThreadState Proprietà

Definizione

Spazio dei nomi:

System.Threading

Assembly:

System.Threading.Thread.dll

Ottiene un valore contenente gli stati del thread corrente.

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

Valore della proprietà

ThreadState

Uno dei valori di ThreadState che indica lo stato del thread corrente. Il valore iniziale è Unstarted.

Esempio

Nell'esempio di codice seguente viene illustrato l'accesso all'oggetto ThreadState di un 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

open System.Threading

let threadMethod () =
    Thread.Sleep 1000

let newThread = Thread threadMethod

printfn $"ThreadState: {newThread.ThreadState}"
newThread.Start()

// Wait for newThread to start and go to sleep.
Thread.Sleep 300
printfn $"ThreadState: {newThread.ThreadState}"

// Wait for newThread to restart.
Thread.Sleep 1000
printfn $"ThreadState: {newThread.ThreadState}"

// 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

Commenti

La ThreadState proprietà fornisce informazioni più specifiche rispetto alla IsAlive proprietà .

Importante

Lo stato del thread è di interesse solo per gli scenari di debug. Il codice non deve mai usare lo stato del thread per sincronizzare le attività dei thread.
