| Exception | Condition |

| ArgumentNullException | The property is being set to null. |
| InvalidOperationException | The property is being set and the DateTimeFormatInfo object is read-only. |
The "F" standard format string is an alias for the FullDateTimePattern property. In other words, the custom format string assigned to this property defines the format of the result string for the "F" standard format string. For more information, see Standard Date and Time Format Strings.
The value of the FullDateTimePattern property is generated dynamically by concatenating the LongDatePattern and LongTimePattern properties separated by a space. This dynamic assignment occurs under the following conditions:
If the property value is retrieved before it has been explicitly set.
When the value of the LongDatePattern property changes.
When the value of the LongTimePattern property changes.
This property is affected if the value of the Calendar property changes.
The following example displays the value of FullDateTimePattern for a few cultures.
using System; using System.Globalization; public class SamplesDTFI { public static void Main() { // Displays the values of the pattern properties. Console.WriteLine( " CULTURE PROPERTY VALUE" ); PrintPattern( "en-US" ); PrintPattern( "ja-JP" ); PrintPattern( "fr-FR" ); } public static void PrintPattern( String myCulture ) { DateTimeFormatInfo myDTFI = new CultureInfo( myCulture, false ).DateTimeFormat; Console.WriteLine( " {0} {1}", myCulture, myDTFI.FullDateTimePattern ); } } /* This code produces the following output. The question marks take the place of native script characters. CULTURE PROPERTY VALUE en-US dddd, MMMM dd, yyyy h:mm:ss tt ja-JP yyyy'?'M'?'d'?' H:mm:ss fr-FR dddd d MMMM yyyy HH:mm:ss */
