Définition
Important
Certaines informations portent sur la préversion du produit qui est susceptible d’être en grande partie modifiée avant sa publication. Microsoft exclut toute garantie, expresse ou implicite, concernant les informations fournies ici.
Obtient une valeur contenant les états du thread actuel.
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
Valeur de propriété
Une des ThreadState valeurs indiquant l’état du thread actuel. La valeur initiale est Unstarted.
Exemples
L’exemple de code suivant illustre l’accès à un ThreadState thread.
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
Remarques
La ThreadState propriété fournit des informations plus spécifiques que la IsAlive propriété.
Important
L’état du thread n’est intéressant que dans les scénarios de débogage. Votre code ne doit jamais utiliser l’état du thread pour synchroniser les activités des threads.
