c# - Access HttpContext.Current.Application from batch process c#

Question

I have a C# ASP.NET web application which starts a thread running some methods in a class called SiteCrawler.cs.

In HttpContext.Current.Application I want to save some value when all the threads are finished running. My problem is that the HttpContext.Current object is null in the spawned threads because it doesn't exist there.

I have tried to search around every inch of Stackoverflow to find a solution but without any luck....

我建议在生成线程时将 HttpContext 作为参数传递。就个人而言，我会删除您对 HttpContext 的依赖并创建一个对象，其工作是同步您的线程（或存储它们的结果），并可用于在并行处理完成后执行后期处理。

HttpContext.Current.Application 是一个单例，它将存在于所有线程中......这是一个网络应用程序吗？如果不是，您始终可以自己初始化应用程序并将其分配给 HttpContext.Current.Application。
