Multithreading in C# is a process in which multiple threads work simultaneously. It is a process to achieve multitasking. It saves time because multiple tasks are being executed at a time. To create multithreaded application in C#, we need to use System.Threding namespace.
The System.Threading namespace contains classes and interfaces to provide the facility of multithreaded programming. It also provides classes to synchronize the thread resource. A list of commonly used classes are given below:
A process represents an application whereas a thread represents a module of the application. Process is heavyweight component whereas thread is lightweight. A thread can be termed as lightweight subprocess because it is executed inside a process.
Whenever you create a process, a separate memory area is occupied. But threads share a common memory area.
