c# - 是否可以将配置发送到 IRecurringJobManager 的 methodCall？

Question

我有变量Configuration（IConfiguration接口），我试图将其作为参数发送到 IRecurringJobManager的调用方法中。但是，当我开始项目时出现错误。

下面是 StartUp.cs 中的 Configure 方法。

public void Configure(IApplicationBuilder app, IWebHostEnvironment env, IRecurringJobManager recurringJobManager, IBackgroundJobClient backgroundJobClient)
{
    ...
            
    recurringJobManager.AddOrUpdate("Run every monday", () => Uploader.Execute(Configuration), "20 1 * * MON", TimeZoneInfo.Local);
}

Uploader是一个具有Execute方法的类，我需要在其中使用一些配置变量。

有趣的是，我能够从控制器发送配置而不会出现任何错误。

[HttpGet]
public ActionResult UploadSales()
{
    try
    {
        Uploader.Execute(Configuration);
    }
    catch (Exception e)
    {
        Logger.WriteLog(e.Message, "Файлы не выгружены");
        throw;
    }

    return Ok("Файлы выгружены успешно");
}
