c# - .net-4.6中的异步Thread.CurrentThread.CurrentCulture

由于Microsoft提供了以下信息，因此我对代码进行了一些更新。听起来他们将当前的文化更新为我可以使用的东西。

using System;
using System.Globalization;
using System.Threading;
using System.Threading.Tasks;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("start " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
        RunAsync().Wait();
        Console.WriteLine("Finish " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
        Console.ReadKey();
    }

    static async Task RunAsync()
    {
        Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("de-DE");

        Console.WriteLine("1 " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
        string cultureInTask = string.Empty;

        await Task.Run(() => cultureInTask = Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId).ConfigureAwait(true);

        Console.WriteLine("2 " + cultureInTask);
        string twoA = await TestMethodAsync();
        Console.WriteLine("2a " + twoA + " " + Thread.CurrentThread.ManagedThreadId);
        Console.WriteLine("3 " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
    }

    public static async Task<string> TestMethodAsync()
    {
        Console.WriteLine("2s " + Thread.CurrentThread.CurrentCulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId);
        return await Task.Run(() =>
        {
            return System.Threading.Thread.CurrentThread.CurrentUICulture.ToString() + " " + Thread.CurrentThread.ManagedThreadId;
        });
    }
}

输出:

start en-US 1
1 de-DE 1
2 de-DE 3
2s de-DE 3
2a en-US 4 4
3 de-DE 4
Finish en-US 1

但是为什么2a返回美国而不是de-DE？是因为executionContext不同吗？如果是这样，我如何才能留在相同的执行上下文中？

最佳答案

CurrentCulture和CurrentUICulture是独立的属性。您只设置CurrentCulture，并且在除2a以外的所有位置报告该位置，该位置报告CurrentUICulture。如果您在代码中始终使用相同的属性(两个属性都可以)，它将为您带来预期的结果。
