占位符在C＃中的线程上下文存储温度值 [英] placeholder for storing temp values in c# thread context

问题描述

我要存储在C＃中的线程上下文或类似的（就像HttpContext的一个Web请求）一些信息（键值对）。

I want to store some info (key value pair) in a c# thread context or similar ( just like httpcontext for a web request ).

我想成为能够存储该信息（键值对）线程上下文（或类似的东西），使我的代码总是可以读取当前线程其下运行的这些值的某个地方。

I want to be able to store this info (key value pair) somewhere in thread context ( or something similar) so that my code can always read these values from the current thread its running under.

在我appliation我有API的调用链及其不可能从一个方法到其他通过该信息（已dsicarded这个选项！）

In my appliation i have a chain of API calls and its not possible to pass this info from one method to other ( already dsicarded this option! )

注意 - 这个线程运行作为一个Asp.Net应用程序中的异步操作。

note - this thread is running as an async operation inside an Asp.Net application.

推荐答案

您寻找< A HREF =http://msdn.microsoft.com/en-us/library/6sby1byh.aspx相对=nofollow>螺纹使用的 ThreadStatic属性的？

public static class ThreadLocalExample
{
    // There will be one Foo instance per thread.
    // Each thread will have to initialize it's own instance.
    [ThreadStatic]
    private static Foo bar;
}

当然，你可以添加一些辅助方法或属性上面来帮助你管理实例，包括确保在每个线程上的初始化。

Of course you could add some helper methods or properties to the above to help you manage the instance, including ensuring initialization on each thread.
