ThreadInterruptedException Class
The exception that is thrown when a Thread is interrupted while it is in a waiting state.
Assembly: mscorlib (in mscorlib.dll)
After a thread is created, it is in one or more ThreadState states until it is destroyed. Calling Interrupt when a thread is in the WaitSleepJoin state will cause a ThreadInterruptedException to be thrown in the target thread. If the thread is not in the WaitSleepJoin state, the exception is not thrown until the thread enters that state. If the thread never blocks, it could complete without ever being interrupted.
ThreadInterruptedException uses the HRESULT COR_E_THREADINTERRUPTED, which has the value 0x80131519.
For a list of initial property values for an instance of ThreadInterruptedException, see the ThreadInterruptedException constructors.
The following code example shows the behavior of a running thread when it is interrupted and subsequently gets blocked.
