.NET Thread.Abort again
- by hoodoos
Again I want to talk about safety of the Thread.Abort function. I was interested to have some way to abort operations which I can't control really and don't want actually, but I want to have my threads free as soon as possible to prevent thread thirsty of my application.
So I wrote some test code to see if it's possible to use Thread.Abort and have the aborting thread clean up resources propertly. Here's code:
int threadRunCount = 0;
int threadAbortCount = 0;
int threadFinallyCount = 0;
int iterations = 0;
while( true )
{
Thread t = new Thread( () =>
{
threadRunCount++;
try
{
Thread.Sleep( Random.Next( 45, 55 ) );
}
catch( ThreadAbortException )
{
threadAbortCount++;
}
finally
{
threadFinallyCount++;
}
} );
t.Start();
Thread.Sleep( 45 );
t.Abort();
iterations++;
}
So, so far this code worked for about 5 mins, and threadRunCount was always equal to threadFinally and threadAbort was somewhat lower in number, because some threads completed with no abort or probably got aborted in finally.
So the question is, do I miss something?
