Calling a method every x minutes
提问by user1765862
I want to call some method on every 5 minutes. How can I do this?
我想每 5 分钟调用一次方法。我怎样才能做到这一点？
public class Program
{
static void Main(string[] args)
{
Console.WriteLine("*** calling MyMethod *** ");
Console.ReadLine();
}
private MyMethod()
{
Console.WriteLine("*** Method is executed at {0} ***", DateTime.Now);
Console.ReadLine();
}
}

var startTimeSpan = TimeSpan.Zero;
var periodTimeSpan = TimeSpan.FromMinutes(5);
var timer = new System.Threading.Timer((e) =>
{
MyMethod();
}, null, startTimeSpan, periodTimeSpan);

Use a Timer. Timer documentation.
使用一个Timer. 定时器文档。

while (true)
{
Thread.Sleep(60 * 5 * 1000);
Console.WriteLine("*** calling MyMethod *** ");
MyMethod();
}

I based this on @asawyer's answer. He doesn't seem to get a compile error, but some of us do. Here is a version which the C# compiler in Visual Studio 2010 will accept.
我基于@asawyer 的回答。他似乎没有收到编译错误，但我们中的一些人却收到了。这是 Visual Studio 2010 中的 C# 编译器将接受的版本。
var timer = new System.Threading.Timer(
e => MyMethod(),
null,
TimeSpan.Zero,
TimeSpan.FromMinutes(5));

Example of using a Timer:
使用 a 的示例Timer：
using System.Timers;
static void Main(string[] args)()
{
Timer t = new Timer(TimeSpan.FromMinutes(5).TotalMilliseconds); // Set the time (5 mins in this case)
t.AutoReset = true;
t.Elapsed += new System.Timers.ElapsedEventHandler(your_method);
t.Start();
}
// This method is called every 5 mins
private void your_method(object sender, ElapsedEventArgs e)
{
Console.WriteLine("...");
}

Start a timer in the constructor of your class. The interval is in milliseconds so 5*60 seconds = 300 seconds = 300000 milliseconds.
在类的构造函数中启动计时器。间隔以毫秒为单位，所以 5*60 秒 = 300 秒 = 300000 毫秒。
static void Main(string[] args)
{
System.Timers.Timer timer = new System.Timers.Timer();
timer.Interval = 300000;
timer.Elapsed += timer_Elapsed;
timer.Start();
}
Then call GetData()in the timer_Elapsedevent like this:
然后调用GetData()在timer_Elapsed这样的事件：
static void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
{
//YourCode
}

I've uploaded a Nuget Package that can make it so simple, you can have it from here ActionScheduler
我上传了一个 Nuget 包，它可以让它变得如此简单，你可以从这里获取它ActionScheduler
It supports .NET Standard 2.0
它支持 .NET Standard 2.0
And here how to start using it
在这里如何开始使用它
using ActionScheduler;
var jobScheduler = new JobScheduler(TimeSpan.FromMinutes(8), new Action(() => {
//What you want to execute
}));
jobScheduler.Start(); // To Start up the Scheduler
jobScheduler.Stop(); // To Stop Scheduler from Running.
