masterpage initializeculture没有找到合适的方法来覆盖错误？

protected override void InitializeCulture()
{
    if (Request.UserLanguages != null && Request.UserLanguages.Length > 0)
    {
        UICulture = Request.UserLanguages[0];
        Culture = Request.UserLanguages[0];
    }
    base.InitializeCulture();
}

protected void Page_Load(object sender, EventArgs e)
{
    InitializeCulture();
    // 其他页面加载逻辑
}

protected void Application_BeginRequest(object sender, EventArgs e)
{
    HttpContext.Current.Response.AddHeader("pragma", "no-cache");
    HttpContext.Current.Response.AddHeader("cache-control", "no-cache, must-revalidate");
    HttpContext.Current.Response.AddHeader("expires", "0");
    HttpContext.Current.Response.CacheControl = "no-cache";
    HttpContext.Current.Response.Cache.SetExpires(DateTime.Now.AddSeconds(-1));
    HttpContext.Current.Response.Cache.SetValidUntilExpires(false);
    HttpContext.Current.Response.Cache.SetRevalidation(HttpCacheRevalidation.AllCaches);
    HttpContext.Current.Response.Cache.SetCacheability(HttpCacheability.NoCache);
}
