DateTimeFormatInfo.ShortDatePattern Property
Gets or sets the format pattern for a short date value, which is associated with the "d" format pattern.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System.StringThe format pattern for a short date value, which is associated with the "d" format pattern.
| Exception | Condition |
|---|---|
| ArgumentNullException | The property is being set to null. |
| InvalidOperationException | The property is being set and the DateTimeFormatInfo object is read-only. |
See Custom Date and Time Format Strings for patterns that can be combined to construct custom patterns, for example, "MM/dd/yyyy".
This property is affected if the value of the Calendar property changes.
The DateSeparator property is derived from the ShortDatePattern property. Your applications are recommended to set the short date pattern to the exact value of interest, instead of attempting to have the date separator replaced. For example, to obtain the pattern MM-DD-yyyy, the application should set "MM-DD-yyyy" specifically. This also permits the setting of patterns such as "MM/DD, yyyy" that don't contain a traditional separator between all parts of the format.
The following example displays the value of the ShortDatePattern property and the value of a date formatted using the ShortDatePattern property for a few cultures.
using System; using System.Globalization; public class SamplesDTFI { public static void Main() { string[] cultures = { "en-US", "ja-JP", "fr-FR" }; DateTime date1 = new DateTime(2011, 5, 1); Console.WriteLine(" {0,7} {1,19} {2,10}\n", "CULTURE", "PROPERTY VALUE", "DATE"); foreach (var culture in cultures) { DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture(culture).DateTimeFormat; Console.WriteLine(" {0,7} {1,19} {2,10}", culture, dtfi.ShortDatePattern, date1.ToString("d", dtfi)); } } } // The example displays the following output: // CULTURE PROPERTY VALUE DATE // // en-US M/d/yyyy 5/1/2011 // ja-JP yyyy/MM/dd 2011/05/01 // fr-FR dd/MM/yyyy 01/05/2011
The following example modifies the ShortDatePattern property of a DateTimeFormatInfo object that represents the formatting conventions of the English (United States) culture. It also displays a date value twice, first to reflect the original ShortDatePattern property and then to reflect the new property value.
using System; using System.Globalization; public class Example { public static void Main() { DateTimeFormatInfo dtfi = CultureInfo.CreateSpecificCulture("en-US").DateTimeFormat; DateTime date1 = new DateTime(2011, 5, 1); Console.WriteLine("Original Short Date Pattern:"); Console.WriteLine(" {0}: {1}", dtfi.ShortDatePattern, date1.ToString("d", dtfi)); dtfi.DateSeparator = "-"; dtfi.ShortDatePattern = @"yyyy/MM/dd"; Console.WriteLine("Revised Short Date Pattern:"); Console.WriteLine(" {0}: {1}", dtfi.ShortDatePattern, date1.ToString("d", dtfi)); } } // The example displays the following output: // Original Short Date Pattern: // M/d/yyyy: 5/1/2011 // Revised Short Date Pattern: // yyyy/MM/dd: 2011-05-01
