DateTimeFormatInfo.CurrentInfo.LongTimePattern not updating

I am using this to read the current long time pattern in Windows:

System.Globalization.DateTimeFormatInfo.CurrentInfo.LongTimePattern

However, if I make a change in the regional settings in the Control Panel, this pattern isn't updated until I restart my application. How can I force this pattern to update when the regional settings are changed?

Solution

  • The values are cached. There is a method to clear this. CultureInfo.ClearCachedData().

    Side note: back in the days of .NET 1.x, this method didn't exist. You had to use reflection to null out the private field. Good times :)
