ThreadInterruptedException クラス

.NET Framework クラス ライブラリ リファレンス

ThreadInterruptedException クラス

Thread が待機状態のときに中断されるとスローされる例外。

名前空間: System.Threading
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public Class ThreadInterruptedException
    Inherits SystemException

Visual Basic (使用法)

Dim instance As ThreadInterruptedException

C#

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public class ThreadInterruptedException : SystemException

C++

[SerializableAttribute] 
[ComVisibleAttribute(true)] 
public ref class ThreadInterruptedException
 : public SystemException

J#

/** @attribute SerializableAttribute() */ 
/** @attribute ComVisibleAttribute(true) */ 
public class ThreadInterruptedException extends
 SystemException

JScript

SerializableAttribute 
ComVisibleAttribute(true) 
public class ThreadInterruptedException extends
 SystemException

解説

スレッドは、作成されてから破棄されるまでの間に、1 回以上 ThreadState 状態になります。スレッドが WaitSleepJoin 状態のときに Interrupt を呼び出すと、ターゲット スレッドで ThreadInterruptedException がスローされます。スレッドが WaitSleepJoin 状態でない場合は、スレッドがその状態になるまで例外はスローされません。スレッドがブロックしない場合、そのスレッドは中断されることなく完了します。

ThreadInterruptedException は、値 0x80131519 の HRESULT COR_E_THREADINTERRUPTED を使用します。

ThreadInterruptedException のインスタンスの初期プロパティ値の一覧については、ThreadInterruptedException コンストラクタのトピックを参照してください。

使用例

実行中のスレッドが中断され、その後ブロックされたときの動作の例を次に示します。
