C# Multithreading: Thread, Task & Parallel

In C#, there are several ways to use multithreading.

1. Using the Thread class: You can create a new thread by instantiating the Thread class and calling its Start method.
2. Using the ThreadPool class: The ThreadPool class provides a thread pool, where work items can be added and executed using the QueueUserWorkItem method.
3. The Task class in .NET Framework is used for managing concurrent tasks, allowing tasks to be executed by creating a Task object and calling its Start method.
4. Utilize the Parallel class: The Parallel class offers a set of static methods that can be used to concurrently execute tasks, such as the Parallel.For and Parallel.ForEach methods.
5. You can use the async and await keywords to create asynchronous methods and manage asynchronous operations using the Task class.

These are several commonly used ways of multi-threading, developers can choose the appropriate method according to specific needs to implement concurrent operations.
