Thread synchronization and locking
When using multiple threads in an application, you have to consider thread synchronization and locking. If you don’t, you can end up with race conditions and deadlocks. There are several ways to synchronize threads. You can use interlocked methods and synchronization objects, such as Monitor, Semaphore, and ManualResetEvent.
Note
In Chapter 8, Threading and Concurrency, in the Clean Code in C# book, we provide a detailed discussion on threads covering using threads, thread safety, parallel threads using semaphores, thread synchronization and preventing deadlocks, and race conditions.
To synchronize your code, you can use a lock object as follows:
internal class LockMutexExample
{
public object _lockObject = new();
public void UsingLockObject()
{
lock(_lockObject)
{
// Perform your unsafe code here.
}
}
}
When the locked code is entered, all of the other threads are barred from accessing the locked...
