什么“当前"属性与 ExecutionContext 一起流动 [英] What "Current" properties flow with ExecutionContext

问题描述

这是一个由两部分组成的问题:

This is a two part question:

1. 谁能提供一个 ASP.NET/.NET 属性的列表，这些属性通常是与 ExecutionContext 一起流动的本地线程?

1. Can someone provide a list of the ASP.NET/.NET properties that are typically thread local that flow with ExecutionContext?

HttpContext.Current?Thread.CurrentContext?Thread.CurrentPrincipal?Thread.CurrentCulture?

HttpContext.Current? Thread.CurrentContext? Thread.CurrentPrincipal? Thread.CurrentCulture?

我可以依靠哪些属性来生存/持久化 async/await?

What properties can I count on surviving/persisting async/await?

还有什么?

有什么方法可以添加特定于应用程序的上下文信息，这些信息将随 ExecutionContext 自动流动?类似的东西

Is there any way to add application specific Context information that will flow automatically with ExecutionContext? Something like

var ec = ExecutionContext.Capture();
ec.CustomContext["MyCustomContext"] = ACustomContext;

推荐答案

最好的资源是 ExecutionContext vs. SynchronizationContext 作者:Stephen Toub.没有您正在寻找的属性列表.

The best resource for this is ExecutionContext vs. SynchronizationContext by Stephen Toub. There is no list of properties like what you're looking for.

ASP.NET 实际上使用 SynchronizationContext 来传输 HttpContext.Current 和 对待Thread.CurrentPrincipal 相当奇怪.

ASP.NET actually uses SynchronizationContext to flow HttpContext.Current, and treats Thread.CurrentPrincipal rather oddly.

您可以使用 LogicalSetData/LogicalGetData 添加您自己的上下文.但是，您应该只存储不可变数据.我在在我的博客上记录了这一点.

You can add your own context using LogicalSetData/LogicalGetData. However, you should only store immutable data. I document this on my blog.
