Is it possible to somehow invoke inline try statement in C#?

I'm detecting languages for my website and sometimes, when language is something like en-GR on client side for some reason .NET throws exception. So I need to use try and also catch even though I'm not really catching anything.

It just seems as a total overkill in this situation.

// Set allowed languages
string[] allowedLanguages = { "en", "fr", "ru" };

// Get all possible values
var routeLanguage = (filterContext.RouteData.Values["lang"] != null && allowedLanguages.Contains(filterContext.RouteData.Values["lang"].ToString())) ? filterContext.RouteData.Values["lang"].ToString() : null;
var cookieLanguage = (filterContext.HttpContext.Request.Cookies["lang"] != null && allowedLanguages.Contains(filterContext.HttpContext.Request.Cookies["lang"].Value)) ? filterContext.HttpContext.Request.Cookies["lang"].Value : null;
string clientLanguage = null;
try
{
    clientLanguage = (filterContext.HttpContext.Request.UserLanguages != null) ? new CultureInfo(filterContext.HttpContext.Request.UserLanguages[0]).TwoLetterISOLanguageName : null; // Exception sometimes without `try`
}
catch (Exception)
{
}

Edit

Exception is not something I can fix since I have no control over what user has in his culture info. .NET just sees en-FR as invalid one.

c# exception try-catch
