c# Task cancellation when using System.Timers

阅读更多关于 c# Task cancellation when using System.Timers

问题 I'm unsure how best to cancel a task that is running a system timer. In the code below, every 60 mins the timer will elapse and then run another method (CheckFileOverflow) that is used to check the file size of a system log txt. file Cancellation of the timer ideally would be done by a button click or another method that calls the cancellation. The timer will effectively be allowed to run for as long as the software is running, but when the user eventually shuts down the software i'd like to

How should the clean-up of Timers declared inside the scope of a function be managed?

问题 In the following code, a Timer is declared inside a function, where it also subscribes to the Elapsed event: void StartTimer() { System.Timers.Timer timer = new System.Timers.Timer(1000); timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed); timer.AutoReset = false; timer.Start(); } Once the function completes, the reference to the Timer is lost (I presume). Does the Elapsed event get unregistered automatically as the object is destroyed, or if not, can the event be

问题 I have an application that I need to have wait a specific amount of time, but I also need to be able to cancel the current operation if needed. I have the following code: private void waitTimer(int days) { TimeSpan waitTime = TimeSpan.FromDays(days); System.Timers.Timer timer = new System.Timers.Timer(waitTime.TotalMilliseconds); // Wait for some number of milliseconds timer.Enabled = true; timer.Start(); timer.Elapsed += new ElapsedEventHandler(OnTimedEvent); // Subscribe to event handler

C#: Best way to achieve a nicely formatted time string?

阅读更多关于 C#: Best way to achieve a nicely formatted time string?

问题 I am writing this question as I am asking for the best way to do this. I have many of these in my program and I want to make a method to convert a Int32 which contains a seconds of a timer into a nicely formatted string. So for example, if my timer int was at lets say a random number like 16429 it would be: 4 hours, 32 minutes and 9 seconds If it was 600, it would be: 10 minutes If it was 60, it would be 1 minute If it was 172801, it would be 2 days and 1 second If it was 32, it would be 32

System.Timers.Timer How to get the time remaining until Elapse

阅读更多关于 System.Timers.Timer How to get the time remaining until Elapse

问题 Using C#, how may I get the time remaining (before the elapse event will occur) from a System.Timers.Timer object? In other words, let say I set the timer interval to 6 hours, but 3 hours later, I want to know how much time is remaining. How would I get the timer object to reveal this time remaining? 回答1: The built-in timer doesn't provide the time remaining until elapse. You'll need to create your own class which wraps a timer and exposes this info. Something like this should work. public

Multiple timer elapsed issue

阅读更多关于 Multiple timer elapsed issue

问题 I have a timer as defined below. The timer executes a long running task. The problem i have is when the timer is running the interval has elapsed again and another timer execution starts i.e _timer_Elapsed . How can i get the timer to execute one interval after the timer has finished. The way it is now there could be multiple timer executions happening at once and that causes all sorts of issues with my code. protected override void OnStart(string[] args) { _timer = new System.Timers.Timer();

C# System.Timers.Timer odd behavior?

阅读更多关于 C# System.Timers.Timer odd behavior?

问题 My goal is to write a code snippet that lets me have an exclusive access to an object (f.ex a txt file) in concurrent environment. With this in mind I was testing the simple program built on use of two System.Timers timers. Event handlers of both timers share the same lock object (Please see the code below). The timers start simultaneously with different interval, 3s for timer1 and 1s for timer2. Timer1 supposed to work only for one cycle, during which it's event handler will sleep for 10s
