What causes system threading ThreadAbortException?

What causes system threading ThreadAbortException?

When a call is made to the Abort method to destroy a thread, the common language runtime throws a ThreadAbortException. When this exception is raised, the runtime executes all the finally blocks before ending the thread. Because the thread can do an unbounded computation in the finally blocks or call Thread.

What is thread abortion?

If the thread that calls Abort holds a lock that the aborted thread requires, a deadlock can occur. If Abort is called on a thread that has not been started, the thread will abort when Start is called. If Abort is called on a thread that is blocked or is sleeping, the thread is interrupted and then aborted.

How do you catch ThreadAbortException?

ThreadAbortException cannot be caught “completely”; it will automatically be rethrown at the end of the catch block (see the linked MSDN docs page) unless Thread. ResetAbort is called first. But this has a really evil smell. There’s probably no reason to do it, so you may want to rethink your approach.

How can you tell if a thread is completed in C#?

How to check whether a thread is alive or not in C#

1. Syntax: public bool IsAlive { get; }
2. Return Value: This property returns true if the thread is started and not terminated normally or aborted.
3. Example 1:
4. Output: Is main thread is alive ? :
5. Example 2:

How do you end a thread in C#?

In C#, a thread can be terminated using Abort() method….Important Points:

1. A deadlock can occur if the thread that calls Abort methods holds a lock that the aborted thread requires.
2. If the Abort method is called on a thread which has not been started, then that thread will abort when Start is called.

Why do I keep getting exception thrown in threading?

In theory, if you use this code, it shouldn’t happen: That being said, I still got these sometimes, which is really surprising. I am guessing that it sometimes occurs in the presence of an active finally block to signal the code to start cleaning itself up, although that doesn’t seem to be the case for you.

What is the null value for threadabortexception?
