如何从.net核心中的Worker返回响应

Question

我已经在.net核心中创建了一个工人，该工人可以计算斐波那契数列。但是我需要能够阅读本系列文章，作为这位工作人员的回应。我对此很陌生，因此经过数小时的研究，我找不到解决方案。

这是我的代码：

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

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

    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        stoppingToken.ThrowIfCancellationRequested();

        await CreateFibonacciSeries();

    }
    public Task<string> CreateFibonacciSeries()
    {
        int a = 0, b = 1, c = 0;
        StringBuilder fiboSeries = new StringBuilder();
        fiboSeries.Append(a + "," + b);

        for (int i = 2; i < 50; i++)
        {
            c = a + b;

            fiboSeries.Append("," + c);
            a = b;
            b = c;
        }
        _logger.LogInformation(fiboSeries.ToString());
        return Task.FromResult(fiboSeries.ToString());
    }
}

和program.cs：

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

    public static IHostBuilder CreateHostBuilder(string[] args) =>
        Host.CreateDefaultBuilder(args)
        .UseWindowsService()
            .ConfigureServices((hostContext, services) =>
            {
                services.AddHostedService<FibonacciCalculateWorker>();
            });

任何建议将不胜感激。
