Gets or sets the time, in milliseconds, before the Tick event is raised relative to the last occurrence of the Tick event. Gets or sets the ISite of the Component. Creates an object that contains all the relevant information required to generate a proxy used to communicate with a remote object.
Releases all resources used by the Component. Retrieves the current lifetime service object that controls the lifetime policy for this instance. Returns an object that represents a service provided by the Component or by its Container. Gets the Type of the current instance. Creates a shallow copy of the current Object. Creates a shallow copy of the current MarshalByRefObject object.
Raises the Tick event. Returns a string that represents the Timer. Occurs when the component is disposed by a call to the Dispose method. Skip to main content.

Timer and Monitor. Timer , this timer is derived from System. Component , allowing it to be used in design surface of Visual Studio. So that it would be only useful if you want a timer on a design surface. He prefers to use System. Timer for background tasks on a thread pool thread. It is interesting to mention that System. Timer was deprecated with. NET Core 1. NET Core 2. NET Standard 2. The goal with.
NET Framework which is probably the reason it came back. When it was deprecated, the. Timer instead. Looks like that Microsoft favors System. Timer before System. One important difference not mentioned above which might catch you out is that System. Timer silently swallows exceptions, whereas System. Timer doesn't. I found a short comparison from MSDN. Timer , which fires an event and executes the code in one or more event sinks at regular intervals. The class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime.
Timer , which executes a single callback method on a thread pool thread at regular intervals. The callback method is defined when the timer is instantiated and cannot be changed. Like the System. Timer class, this class is intended for use as a server-based or service component in a multithreaded environment; it has no user interface and is not visible at runtime. Timer , a Windows Forms component that fires an event and executes the code in one or more event sinks at regular intervals.
The component has no user interface and is designed for use in a single-threaded environment. Timer , an ASP. NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
Timer is a simple, lightweight timer that uses callback methods and is served by thread pool threads. It is not recommended for use with Windows Forms, because its callbacks do not occur on the user interface thread. Timer is a better choice for use with Windows Forms. For server-based timer functionality, you might consider using System. Timer , which raises events and has additional features. The two classes are functionally equivalent, except that System. Timer has an option to invoke all its timer expiration callbacks through ISynchronizeInvoke by setting SynchronizingObject.
Otherwise, both timers invoke expiration callbacks on thread pool threads. NET component that performs asynchronous or synchronous web page postbacks at a regular interval.
It is a UI timer. Posted On: Mar SignalR for real-time web functionality. MVC Design pattern. Is Programming an Art or a Science? Ignore case in String. Replace using StringComparison. To ensure it will run in one thread he decided to have lock , like in code below:.
Yes, this code ensures that section under lock is executed in one thread. And you know this code works well unless your execution takes few hours and you will be out of threads and out of memory. My first idea was to change this timer to the System. Timer, and it worked well in application, but that application is able to run in GUI and WinService modes. But there are so many complains over interned to do not use Forms. Timer for non UI stuff. Also if you put Forms.
Timer into your console application it will simply not work. Timer is just wrapper over System. Timer, but what is very interesting is that it provides us with more developer-friendly abilities like enabling and disabling it. My final decision which fixes issue is to disable timer when we are diving into our operation and enable on exit. In my app timer executes every 30 seconds so this could not be a problem. Fix looks like:. The way disabling and enabling the timer was eye-opening to me as I'm a newcomer to Threading.
Your solutions and explanation really taught me good points. Thanks for your posting.
