Setting thread Culture to a neutral culture

Question

When try to save data to database with db_ent.SaveChanges() I have this error:

Culture 'sr' is a neutral culture. It cannot be used in formatting and parsing and therefore cannot be set as the thread's current culture. Any solutions for this?

Edit:

My RouteLocalization Helper

        var ci = new CultureInfo(culture);
        Thread.CurrentThread.CurrentUICulture = ci;
        Thread.CurrentThread.CurrentCulture = CultureInfo.CreateSpecificCulture(ci.Name);
        return base.GetHttpHandler(requestContext);
    }
}

public class SingleCultureMvcRouteHandler : MvcRouteHandler {}

public class CultureConstraint : IRouteConstraint

    public bool Match(HttpContextBase httpContext,Route route,string parameterName,

    {
        // Get the value called "parameterName" from the

        // Return true is the list of allowed values contains 
        // this value.
        return _values.Contains(value);
    }
}

    sr = 1,
    hr = 2,
    en = 3,
    ru = 4

    {
        Key = key;
        Message = message;
    }
}

I had a similar problem. User's browser was sending 'en' neutral culture.

So I used this to get .Net to pick the closest 'specific' culture:

//replace '$' in string with current user's culture's Currency Symbol
//if neutral culture use .Net to set SpecificCulture
//, e.g. 'en', .Net assumes 'en-US'
private static MvcHtmlString currencySubstitution(MvcHtmlString htmlString)
    {
        var ci = System.Threading.Thread.CurrentThread.CurrentUICulture;
        System.Globalization.RegionInfo ri;
        if (ci.IsNeutralCulture)
        {
            ci = System.Globalization.CultureInfo.CreateSpecificCulture(ci.TwoLetterISOLanguageName);
        }

        ri = new System.Globalization.RegionInfo(ci.LCID);

        string currencySymbol = ri.CurrencySymbol;//en-AU: $,or // AUD = ri.ISOCurrencySymbol;
        return MvcHtmlString.Create(htmlString.ToHtmlString().Replace("$", currencySymbol));
    }

You can't use a neutral culture (sr, en, fr, etc...) because there may be formatting differences in the specific cultures. For example, en-US and en-GB may format dates differently and just using en won't be able to ensure that formatting will occur correctly.

You have to use a specific culture. In your case instead of just 'sr' try 'sr-Cyrl-CS' (Serbia, Cyrillic) or 'sr-Latn-CS' (Serbia, Latin) cultures instead or perhaps another sr-specific culture name that you know should work.

Is possible change neutral culture in controller action when I post data? – Ognjen Mar 30 '11 at 19:33
I'm not 100% sure but I don't think setting the culture in the action and then immediately trying to save your data will work since the culture change won't complete in the context/thread until after the saving of the data has occured. You really want to know what culture you are using before you do any data processing. – Kevin LaBranche Mar 30 '11 at 19:44
Here's some links on the topic of having MVC change the culture.... http://afana.me/post/aspnet-mvc-internationalization.aspx http://stackoverflow.com/questions/1560796/set-culture-in-an-asp-net-mvc-app – Kevin LaBranche Mar 30 '11 at 19:45
is there way to disable this culture check? I can't use sepcific culture because my localization code is very complicated to change – Ognjen Mar 30 '11 at 20:08

Try sr-Cyrl-RS for cyrillic or sr-Latn-RS for latin.
