Using CultureInfo class in C# to implement Globalization

CultureInfo class provides culture-specific information in .NET applications. This information includes language, sublanguage, country or region, day names, month names, calendar etc. It also provides culture specific conversions of numbers, currencies, dates or strings. In the following tutorial, I will show you how you can retrieve this information from different cultures available in .NET Framework.

To use CultureInfo class you need to import System.Globalization namespace which contains many classes used in the following code such as RegionInfo, DateTimeFormatInfo or NumberFormatInfo.

Globalization using CultureInfo class

Following code is loading all specific cultures available in .NET Framework in the listbox.

private void Form1_Load(object sender, EventArgs e)

      // Load All Specific Cultures
      CultureInfo[] allCultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
      foreach (CultureInfo culture in allCultures)
            listBox1.Items.Add(culture.EnglishName );

When user select any culture from the listbox following code retrieve that culture, set current application and user interface culture and then display culture specific information on different labels.

private void listBox1_SelectedIndexChanged(object sender, EventArgs e)
CultureInfo[] allCultures = CultureInfo.GetCultures(CultureTypes.SpecificCultures);
int index = listBox1.SelectedIndex;
CultureInfo c = (CultureInfo)allCultures.GetValue(index);
// Set Current Application and User Interface Culture
System.Threading.Thread.CurrentThread.CurrentCulture = c;
System.Threading.Thread.CurrentThread.CurrentUICulture = c;
label1.Text = "Application Culture Name: " + c.Name;
label2.Text = "Application Culture Native Name: " + c.NativeName;
label3.Text = "Application Culture English Name: " + c.EnglishName;
label4.Text = "Application Culture Neutral Name: " + c.TwoLetterISOLanguageName;
            label5.Text = "Application Culture Language Name: " + c.ThreeLetterISOLanguageName;
            label6.Text = "Application Culture Windows Name: " + c.ThreeLetterWindowsLanguageName;

            // RegionInfo Object

            RegionInfo r = new RegionInfo(c.Name);

            label7.Text = "Region English Name: " + r.CurrencyEnglishName;
            label8.Text = "Currency Symbol: " + r.CurrencySymbol;
            label9.Text = "Region English Name: " + r.EnglishName;

            // DateTimeFormatInfo Object is used 
            // to get DayNames and MonthNames

            string[] days = c.DateTimeFormat.DayNames;
            foreach (string day in days)

            string[] months = c.DateTimeFormat.MonthNames;
            foreach (string month in months)

            // Formatting Currency and Numbers

            label10.Text = "Full Date Time Pattern: " + c.DateTimeFormat.FullDateTimePattern;
            label11.Text = "Formatted Date: " + DateTime.Now.ToString("d", c.DateTimeFormat);
            label12.Text = "Formatted Number: " + 65000.ToString("C", c.NumberFormat);
      catch (Exception ex)
      { }
