Dear All, I am a beginner in C#. I want to create a class which can insert into any project for managing threads. However I don't know how to do it. Could anybody help me?

.NET already has this as part of the thread pool it manages automatically for you. You don't need to create your own threads unless you have very specific needs such as having multiple long running threads (aka server threads) or similar. For short lived requests everything has switch to tasks as it is easier, cleaner and more efficient in many cases. Can you elaborate on why you need to create a library to manage threads? In general this extra layer isn't going to be useful outside perhaps the server side of a client-server application.

In practice you never need that and you cannot easily write better code than a group of top professionals. Learn Task Parallel Library instead, https://learn.microsoft.com/en-us/dotnet/standard/parallel-programming/task-parallel-library-tpl

Hi @Michael Taylor

Thanks for your reply.

Threads are an impotant thing in c#

Is it possible to write a sample code, with or without the general class, for me?

Threads are not an important aspect of C#. I'm not really sure where you heard that. Multithreading is important to most apps but the best multithreading is one you don't manage. That is why we have the thread pool and that is why tasks have become such a critical part of apps. I can honestly say that in the last 5 years I've written maybe 2 applications that explicitly used threading. In all other cases tasks are used which allow my app to scale up to the needs of the system (large web apps) and never once did I need to be concerned about threading. This is world we live in today, threads are only need for advanced scenarios where you have very specific needs (such as COM interop). And at that point a thread manager is probably not needed.

If you need to get all the running threads in your process use Process.Threads. Given a thread you can pause or terminate it (not recommended) if needed.

foreach (var thread in Process.GetCurrentProcess().Threads) { Console.WriteLine(thread.Id); };

If you want to start some background work on a thread then you can do that as well:

var thread = new Thread(DoWork); thread.IsBackground = true; thread.Start();

If you don't actually need a dedicated thread (the most common case) then use the thread pool instead.

ThreadPool.QueueUserWorkItem(DoWork, myData, false); void DoWork ( MyData data ) { //Running in thread pool }

In genneral though tasks are easier.

async Task DoWorkAsync ( ) { //Current thread //Background thread await DoWorkInBackgroundAsync(); //Back on current thread again }

Again, if you can be more precise about what you're trying to do we can better help you.

Hi @Michael Taylor

Thanks for your reply and advices. I am just thinking thread is an important thing in C# and want to create a general class for it.
