首先创建一个类Background
实现代码:
using Microsoft.Extensions.Hosting;
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace SmartMedicalCare.Web
{
public class Background : IHostedService, IDisposable
{
private Timer? timer;
private void DoWork(object state)
{
Console.WriteLine($"{DateTime.Now:yyyy-MM-dd HH:mm:ss}");
}
public void Dispose()
{
timer?.Dispose();
}
/// <summary>
/// Triggered when the application host is ready to start the service.
/// </summary>
/// <param name="cancellationToken">Indicates that the start process has been aborted.</param>
public Task StartAsync(CancellationToken cancellationToken)
{
timer = new Timer(DoWork, null, TimeSpan.Zero, TimeSpan.FromSeconds(5));
return Task.CompletedTask;
}
public Task StopAsync(CancellationToken cancellationToken)
{
Console.WriteLine("StopAsync");
return Task.CompletedTask;
}
}
}
然后在Program中加入以下代码:
//注册定时任务
builder.Services.AddHostedService<Background>();
如果有Autofac的话前把代码写在AutoFac上面
以上代码实现的是每隔5秒输出当前时间
效果图:
