Put this with the other using statements:
using System.Threading;
using System.Globalization;
Put this as the first line of code in your Main
method:
Thread.CurrentThread.CurrentCulture =
new CultureInfo("nl-NL");
Console.WriteLine("Weekday: {0}", Thread.CurrentThread.CurrentCulture.DateTimeFormat
.GetDayName(DateTime.Today.DayOfWeek));
Then your application will use that culture. It will be used for datetime formatting, number formatting etc.
If you were using a UI application, like windows forms, you would also need to set the ui culture like this:
Thread.CurrentThread.CurrentUICulture =
new CultureInfo("nl-NL");
When you set the CurrentUICulture
then the application will get information from your resources file for displaying labels etc in the UI.
