有几种方法可以设置每种用户语言。IIS服务器保持会话20分钟。您需要通过添加行来更改web.config文件中的时间：

<sessionState timeout="120" cookieless="AutoDetect">
// Change timeout to your preferred value

或者，您需要在应用程序中更改设置。对于我的项目，我使用cookie来保存用户语言选项。Cookies设置为可使用很长时间。例如，我在Global.asax Application_BeginRequest中使用了

protected void Application_BeginRequest(object sender, EventArgs e)
        {
            HttpCookie cookie = HttpContext.Current.Request.Cookies["NAMEOFCOOKIE"];
            if (cookie != null && cookie.Value != null)
            {
                System.Threading.Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo(cookie.Value);
                System.Threading.Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo(cookie.Value);
            }
            else
            {
               // FIND IN DB YOUR USER'S LANGUAGE AND SET IT 
                        Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("YOUR USERS'S DB VALUE");
                        Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("YOUR USERS'S DB VALUE");
                        HttpCookie cookieNew = new HttpCookie("NAMEOFCOOKIE");
                        cookieNew.Value = "YOUR USERS'S DB VALUE";
                        Response.Cookies.Add(cookieNew);
                    }
                }
            }
        }

当你使用资源的时候，不要忘记一件事，你需要把它放在文件名的末尾，你的语言简称。例如，您有默认文件MainPageLang.resx，而您需要英语和俄语，您必须添加文件MainPageLang.en.resx和MainPageLang. ru. resx。
“您的用户数据库值”必须是“en”或“ru”。

Thread.CurrentThread.CurrentCulture = new System.Globalization.CultureInfo("YOUR USERS'S DB VALUE");
                    Thread.CurrentThread.CurrentUICulture = new System.Globalization.CultureInfo("YOUR USERS'S DB VALUE");
                    HttpCookie cookieNew = new HttpCookie("NAMEOFCOOKIE");
                    cookieNew.Value = "YOUR USERS'S DB VALUE";
                    Response.Cookies.Add(cookieNew);

我们能够找到解决问题的办法。需要在所有ResourceName.Designer.cs文件中对此进行更改：

/// <summary>
///   Overrides the current thread's CurrentUICulture property for all
///   resource lookups using this strongly typed resource class.
/// </summary>            [global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]
public static global::System.Globalization.CultureInfo Culture {
    get {
        return resourceCulture;
    }
    set {
        resourceCulture = value;
    }
}

这是：

/// <summary>
///   Overrides the current thread's CurrentUICulture property for all
///   resource lookups using this strongly typed resource class.
/// </summary>
[global::System.ComponentModel.EditorBrowsableAttribute(global::System.ComponentModel.EditorBrowsableState.Advanced)]
public static global::System.Globalization.CultureInfo Culture
{
    get
    {
        return System.Threading.Thread.CurrentThread.CurrentCulture;
    }
    set
    {
        System.Threading.Thread.CurrentThread.CurrentCulture = value;
    }
}
