问当应用程序立即启动时，有什么方法可以执行ExecuteEvery5Min，然后每5分钟通过计时器执行一次吗？

EN

using (UtilityClass utilityClass = new UtilityClass()) // To dispose after the use
        {
            while (true) { }
        }


public class UtilityClass : IDisposable
{
    private readonly System.Timers.Timer _Timer;

    public UtilityClass()
    {
        _Timer = new System.Timers.Timer(TimeSpan.FromMinutes(5).TotalMilliseconds)
        {
            Enabled = true
        };

        _Timer.Elapsed += (sender, eventArgs) =>
        {
            ExecuteEvery5Min();
        };
    }

    private void ExecuteEvery5Min()
    {
        Console.WriteLine($"Every 5 minute at {DateTime.Now}");
    }

    public void Dispose()
    {
        _Timer.Dispose();
    }
}
