How to destroy threads in C#?
The Abort() method is used for destroying threads.
The runtime aborts the thread by throwing a ThreadAbortException. This exception cannot be caught, the control is sent to the finally block, if any.
The following is an example showing how to destroy threads −
Example
using System;
using System.Threading;
namespace MultithreadingApplication {
class ThreadCreationProgram {
public static void CallToChildThread() {
try {
Console.WriteLine("Child thread starts");
// do some work, like counting to 10
for (int counter = 0; counter <= 10; counter++) {
Thread.Sleep(500);
Console.WriteLine(counter);
}
Console.WriteLine("Child Thread Completed");
} catch (ThreadAbortException e) {
Console.WriteLine("Thread Abort Exception");
} finally {
Console.WriteLine("Couldn't catch the Thread Exception");
}
}
static void Main(string[] args) {
ThreadStart childref = new ThreadStart(CallToChildThread);
Console.WriteLine("In Main: Creating the Child thread");
Thread childThread = new Thread(childref);
childThread.Start();
//stop the main thread for some time
Thread.Sleep(2000);
//now abort the child
Console.WriteLine("In Main: Aborting the Child thread");
childThread.Abort();
Console.ReadKey();
}
}
}Output
In Main: Creating the Child thread Child thread starts 0 1 2 In Main: Aborting the Child thread Thread Abort Exception Couldn't catch the Thread Exception
