CultureInfo.CurrentCulture不包含正确的值->数字格式问题

Question

I need to write doubles to a csv file in a wpf mvvm application. These doubles are originally strings set in invariant culture. I recieve them like so from the server side application and parse them with

bool result = double.TryParse(row[0], NumberStyles.Any, CultureInfo.InvariantCulture, out value);  

However when I try to write them to the csv file (either with "" + value , value.ToString() , value.ToString(CultureInfo.CurrentCulture) or value.ToString(System.Globalization.CultureInfo.CurrentCulture) ), the current culture seems to be EN-US while it should be NL (dutch). My browser settings, windows settings, keyboard settings... are all set to dutch, so when I check my regional number settings it contains the decimal separator ",", but my application separates the decimals with "." since the culture is EN-US.

So when I write my csv file and open it in excel it contains decimal values separated with "." instead of ",". This way my excel does not see these values as decimal values since they are not in the excel number culture/my windows settings culture.

Does anyone know what's going on?

Edit

Just to be clear. I'm not looking for a way to set the culture hard coded. I specifically need the culture set in windows, the one which excel uses.

Answer 1

For further reference here's what the problem was:

We have a pretty large application where it is possible to override the culture for datetime display etc... Once you set the current thread culture to a new culture, the original one cannot be accessed anymore.

So to be able to access the windows culture I created a property which remembers the currentculture before it was changed to the user setting of the application and used that one to export my data to a csv file.

Have you override base.InitializeCulture() ;

below sample code is just for understanding..may be you get some idea

    if (Session["CurrentUI"] != null)
    {
        String selectedLanguage = (string)Session["CurrentUI"];
        UICulture = selectedLanguage;
        Culture = selectedLanguage;

        Thread.CurrentThread.CurrentCulture =
            CultureInfo.CreateSpecificCulture(selectedLanguage);
        Thread.CurrentThread.CurrentUICulture = new
            CultureInfo(selectedLanguage);
    }

    base.InitializeCulture();
