C # Console Thread Timer code example

There are three types of timers available in C #:
1. Windows-based standard timer (System.Windows.Forms.Timer)
2. Server-Based Timers (System.Timers.Timer)
3. Thread Timer (System.Threading.Timer)
One, Windows-based standard timer (System.Windows.Forms.Timer)
First, note that the Windows timer is designed for single-threaded environments
This timer is present in the product from the Visual Basic version 1.0 and is basically unchanged
This timer is the simplest one, just drag the Timer control from the Toolbox onto the form, then set the event and interval time properties.
second, server-based Timers (System.Timers.Timer)
System.Timers.Timer does not rely on forms, is a wake-up thread from the thread pool, is an updated version of the classic timer in order to run on a server environment, no ready-made controls are available in the VS2008 Toolbox, and manual encoding is required to use this timer
Three, Thread Timers (System.Threading.Timer)
The thread timer is also not dependent on the form, and is a simple, lightweight timer that uses callback methods instead of using events and is supported by thread pool threads. Thread timers are very useful in scenarios where messages are not sent on threads.

The code example is given only for the use of the console thread timer, followed by several other code examples:
