C# 如何在asp.net mvc中正确检测用户浏览器文化

我看到有类似的问题，但我还没有找到我的问题的答案，因此，我决定问我自己的问题

情况：我想获取用户的浏览器语言，这样我就可以设置他的会话区域性密钥，或者如果用户有帐户，则可以将本地化存储在数据库中，以便在该用户手动更改语言首选项之前，用他的语言向该用户显示我的网站

我的问题是：理论上一切似乎都很好，但

这些是我的浏览器语言首选项 我知道它们是按特定顺序排列的

无论我的浏览器显示语言是否设置为保加利亚语，该命令都会发送到服务器。我的首选项仍然保留在美国

这是一个示例代码片段，用于显示我的开发工具控制台对我的浏览器显示语言的说明

在我的代码中，我不知道什么是浏览器语言，我只能向用户获取首选语言，然后获取语言[0]

有没有办法获得这种显示语言。我无法使用JS发送它，因为我有一个问题，我的第一个请求总是以英语显示页面，而不是在设置会话时显示本地化页面。可能有一种解决方法可以检查和设置JS中的特定头，但我正在考虑一种更大胆的方法，只使用C#

我不确定这是正确的方法。我已经在BaseController中重写了OnActionExecuting，我正在根据用户的区域设置设置当前线程的本地化，他可能会通过下拉其首选语言来更改，该语言也会重写并重置会话语言键。我也知道有一个自动区域设置选项，但我不确定它是否足够好，而且我也不知道它是如何工作的，以及用户如何在自动全球化打开时简单地更改其语言

---

目前，我只想获得适当的浏览器显示语言，我需要处理本地化问题的人员的帮助。

您可以使用CultureHelper：

public static class CultureHelper
{
