ThreadAbortException 类
在对 Abort 方法进行调用时引发的异常。无法继承此类。
**命名空间:**System.Threading
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
<SerializableAttribute> _
<ComVisibleAttribute(True)> _
Public NotInheritable Class ThreadAbortException
Inherits SystemException
用法
Dim instance As ThreadAbortException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public sealed class ThreadAbortException : SystemException
[SerializableAttribute]
[ComVisibleAttribute(true)]
public ref class ThreadAbortException sealed : public SystemException
/** @attribute SerializableAttribute() */
/** @attribute ComVisibleAttribute(true) */
public final class ThreadAbortException extends SystemException
SerializableAttribute
ComVisibleAttribute(true)
public final class ThreadAbortException extends SystemException
备注
在调用 Abort 方法以销毁线程时，公共语言运行库将引发 ThreadAbortException。ThreadAbortException 是一种可捕获的特殊异常，但在 catch 块的结尾处它将自动被再次引发。引发此异常时，运行库将在结束线程前执行所有 finally 块。由于线程可以在 finally 块中执行未绑定计算，或调用 Thread.ResetAbort 来取消中止，所以不能保证线程将完全结束。如果您希望一直等到被中止的线程结束，可以调用 Thread.Join 方法。Join 是一个模块化调用，它直到线程实际停止执行时才返回。
提示
在托管可执行文件中的所有前台线程已经结束后，当公共语言运行库 (CLR) 停止后台线程时，它不使用 System.Threading.Thread.Abort。因此，无法使用 ThreadAbortException 来检测 CLR 何时终止后台线程。
ThreadAbortException 使用值为 0x80131530 的 HRESULT COR_E_THREADABORTED。
提示
继承的 Data 属性的值始终是 空引用（在 Visual Basic 中为 Nothing）。
示例
下面的示例说明如何中止线程。接收 ThreadAbortException 的线程使用 ResetAbort 方法取消中止请求并继续执行。

这段代码产生以下输出：
Thread - working.
Main - aborting my thread.
Thread - caught ThreadAbortException - resetting.
Exception message: Thread was being aborted.
Thread - still alive and working.
Thread - finished working.
Main ending.
