    <remarks>
      <para> Instances of this exception type can only
      be created by the system.</para>
      <para>When a call is made to <see cref="M:System.Threading.Thread.Abort(System.Object)" />
to terminate a thread, the system throws a <see cref="T:System.Threading.ThreadAbortException" /> in the target
thread. <see cref="T:System.Threading.ThreadAbortException" /> is a
special exception that can
be caught by application code, but is rethrown at the end of the catch block
unless <see cref="M:System.Threading.Thread.ResetAbort" /> is called. When the
<see langword="ThreadAbortException " /> 
exception is raised, the system executes any <see langword="finally " />blocks for the target thread. The finally blocks are executed even if
<see cref="M:System.Threading.Thread.ResetAbort" qualify="true" /> is called. If the abort is successful, 
the target thread is left in the <see cref="F:System.Threading.ThreadState.Stopped" qualify="true" /> and
<see cref="F:System.Threading.ThreadState.Aborted" qualify="true" /> states.</para>
    </remarks>
    <example>
      <para>The following example demonstrates aborting a thread.
      The thread that receives the <see cref="T:System.Threading.ThreadAbortException" /> uses the <see cref="M:System.Threading.Thread.ResetAbort" /> method to cancel the abort request and
      continue executing.</para>

          <para>The object returned by this property is specified via the

   <see langword="null" /> if no

      called. The exact content and usage
      of this object is application-defined; it is typically used to convey
      information that is meaningful to the thread being aborted.</para>
