Title: Display sample formats for different locales in C#

When the program starts, the following code executes.

private void Form1_Load(object sender, EventArgs e) { float float_value = 1234.56f; decimal dec_value = 1234.56m; DateTime now = DateTime.Now; // Loop through the locales. foreach (CultureInfo info in CultureInfo.GetCultures(CultureTypes.AllCultures)) { ListViewItem item = lvwResults.Items.Add( info.EnglishName); item.SubItems.Add(info.NativeName); item.SubItems.Add(info.Name); // You can't use a neutral culture as a format // provider, so if the CultureInfo is neutral, // look for a non-neutral ancestor. CultureInfo culture = info; while ((culture != null) && (culture.IsNeutralCulture)) culture = culture.Parent; if (culture != null) { item.SubItems.Add(float_value.ToString("N", culture)); item.SubItems.Add(dec_value.ToString("C", culture)); item.SubItems.Add(now.ToString("d", culture)); item.SubItems.Add(now.ToString("t", culture)); } } }

This code first creates float, decimal, and DateTime sample values. It then loops through the CultureInfo objects returned by CultureInfo.GetCultures.

For each CultureInfo, the code adds the object's English, native, and locale names to the ListView.

Next the code checks whether the object represents a neutral culture such as en. If it does, the object doesn't contain information about a specific culture that is needed to format values. For example, the culture en doesn't contain that information. In contrast, a specific culture such as en-US or en-GB.

If the object does represent a neutral culture, the code climbs up its parent hierarchy until it finds a non-neutral culture and it uses that one.

Having found a non-neutral culture, the program uses the culture to format float, decimal, date, and time values and adds them to the ListView.
