Question

这里有一个很好的主题： Get CultureInfo from current visitor

解释我们可以使用以下方式轻松获取浏览器语言：

var userLanguages = Request.UserLanguages;

这里的问题是，这只给了我在浏览器中配置的语言，但没有给出我选择的语言。同时，数组中的第一种语言（[0]）可能不是活动语言。

有没有办法在服务器端找到活动的？我知道我可以使用javascript在客户端进行，但我想避免双重调用。

您需要通过Cookie设置此信息（可以通过页面上的设置切换）。

public ActionResult SetCulture(string culture) //culture is something like en-US, you can validate it ahead of time.
{
    HttpCookie cookie = Request.Cookies["currentCulture"];
    if (cookie != null)
        cookie.Value = culture;   // update cookie value
    else //create the cookie here
    {
        cookie = new HttpCookie("currentCulture");
        cookie.Value = culture;
        cookie.Expires = DateTime.Now.AddYears(1);
    }
    Response.Cookies.Add(cookie);
    return Redirect(Request.UrlReferrer.ToString()); //send them back to the site they were at (in a translated form).
}

要确定服务器端的文化，只需在执行操作时读取cookie。

protected override IAsyncResult BeginExecuteCore(AsyncCallback callback, object state)
{

    HttpCookie cultureCookie = Request.Cookies["currentCulture"];
    string cultureName = cultureCookie== null ? "en-US" : cultureCookie.Value;        
    if (cultureCookie != null)
        cultureName = cultureCookie.Value;

    // Modify current thread's cultures            
    Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cultureName);
    Thread.CurrentThread.CurrentUICulture = Thread.CurrentThread.CurrentCulture;

    return base.BeginExecuteCore(callback, state);
}

在浏览器上获取选定（活动）语言
