Thread.ThreadState Eigenschaft
Definition
Wichtig
Einige Informationen beziehen sich auf Vorabversionen, die vor dem Release ggf. grundlegend überarbeitet werden. Microsoft übernimmt hinsichtlich der hier bereitgestellten Informationen keine Gewährleistungen, seien sie ausdrücklich oder konkludent.
Ruft einen Wert ab, der die Zustände des aktuellen Threads enthält.
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
Eigenschaftswert
Einer der ThreadState-Werte, der den Zustand des aktuellen Threads angibt. Der Anfangswert ist Unstarted.
Beispiele
Im folgenden Codebeispiel wird der Zugriff auf ThreadState
eines Threads veranschaulicht.
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
Hinweise
Die ThreadState -Eigenschaft stellt spezifischere Informationen als die IsAlive -Eigenschaft bereit.
Wichtig
Der Threadstatus ist nur in Debugszenarien von Interesse. Sie sollten den Threadzustand niemals verwenden, um die Aktivitäten von Threads zu synchronisieren.
