Blazor上执行查询的计数器

顶部：

我在Blazor上有一个柜台：

@inject Services.BlazorTimer Timer

登记如下：

private async Task StartTimer()
{
    Timer.SetTimer(5000);
    Timer.OnElapsed += testTask;
    Console.WriteLine("Timer Started.");
}

private async Task testTask(Object source, ElapsedEventArgs e)
{
    Console.WriteLine("Task done");
}

services.AddTransient<Services.BlazorTimer>();

---

Timer.OneFassed始终为红色。为什么会这样？

您需要添加更多代码

using System.Timers;

namespace BlazorApp6.Services
{
    public class BlazorTimer
    {
        private Timer _timer;

        public void SetTimer(double interval)
        {
            _timer = new Timer(interval);
            _timer.Elapsed += NotifyTimerElapsed;
            _timer.Enabled = true;
        }

        public event Action OnElapsed;
    }
}
