如何创建每隔一段时间运行一次函数的BackGround服务？使用C# (asp.net核心3.1.1)

using System;
using System.Threading;
using System.Threading.Tasks;
using Microsoft.Extensions.Hosting;
using Microsoft.Extensions.Logging;

public class BackgroundServiceExample : BackgroundService
{
    private readonly ILogger<BackgroundServiceExample> _logger;

    public BackgroundServiceExample(ILogger<BackgroundServiceExample> logger)
    {
        _logger = logger;
    }

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        while (!stoppingToken.IsCancellationRequested)
        {
            // 在这里编写你要定时执行的函数逻辑
            _logger.LogInformation("后台服务正在运行...");

            // 暂停一段时间
            await Task.Delay(TimeSpan.FromMinutes(5), stoppingToken);
        }
    }
}

using Microsoft.AspNetCore.Builder;
using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Configuration;
using Microsoft.Extensions.DependencyInjection;
using Microsoft.Extensions.Hosting;

public class Startup
{
    public Startup(IConfiguration configuration)
    {
        Configuration = configuration;
    }

    public IConfiguration Configuration { get; }

    public void ConfigureServices(IServiceCollection services)
    {
        services.AddHostedService<BackgroundServiceExample>();
        services.AddLogging();
        // 添加其他服务配置...
    }

    public void Configure(IApplicationBuilder app, IWebHostEnvironment env)
    {
        // 配置中间件...
    }
}

using Microsoft.AspNetCore.Hosting;
using Microsoft.Extensions.Hosting;

public class Program
{
    public static void Main(string[] args)
    {
        CreateHostBuilder(args).Build().Run();
    }

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
            .ConfigureWebHostDefaults(webBuilder =>
            {
                webBuilder.UseStartup<Startup>();
            });
}
