Methods

Name Description
Equals(Object) Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
Finalize Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)
GetBaseException When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
GetHashCode Serves as a hash function for a particular type. (Inherited from Object.)
GetType Gets the runtime type of the current instance. (Inherited from Exception.)
MemberwiseClone Creates a shallow copy of the current Object. (Inherited from Object.)
ToString Creates and returns a string representation of the current exception. (Inherited from Exception.)

Remarks

When a call is made to the Abort method to destroy a thread, the common language runtime (CLR) throws a ThreadAbortException. ThreadAbortException is a special exception that can be caught, but it will automatically be raised again at the end of the catch block. When this exception is raised, the runtime executes all the finally blocks before ending the thread.

In Windows Phone applications, you cannot abort threads. If a thread in your application receives a ThreadAbortException, it is because the CLR has aborted the thread.

Note

The value of the inherited Data property is always nullNothingnullptra null reference (Nothing in Visual Basic).

When the CLR stops background threads, after all foreground threads in a managed executable have ended, it does not use Thread..::.Abort. Therefore, you cannot use ThreadAbortException to detect when background threads are being terminated by the CLR.
