Gets or sets the custom format string for a month and day value.

Namespace:   System.Globalization
Assembly:  mscorlib (in mscorlib.dll)

Public Property MonthDayPattern As String

Property Value

Type: System.String

The custom format string for a month and day value.

Exception Condition

The property is being set to null.


The property is being set and the DateTimeFormatInfo object is read-only.

The MonthDayPattern property defines the culture-specific format of date strings that are returned by calls to the DateTime.ToString and DateTimeOffset.ToString methods and by composite format strings that are supplied the "m" and "M" standard format strings.

This property is affected if the value of the Calendar property changes.

We recommend that you set the date separator in the month and day pattern to an exact string instead of using the date separator placeholder. For example, to obtain the pattern MM-DD, set the month and day pattern to "MM-DD".

The following example displays the value of MonthDayPattern for a few cultures.

Imports System
Imports System.Globalization

Public Class SamplesDTFI

   Public Shared Sub Main()

      ' Displays the values of the pattern properties.
      Console.WriteLine(" CULTURE    PROPERTY VALUE")

   End Sub 'Main

   Public Shared Sub PrintPattern(myCulture As [String])

      Dim myDTFI As DateTimeFormatInfo = New CultureInfo(myCulture, False).DateTimeFormat
      Console.WriteLine("  {0}     {1}", myCulture, myDTFI.MonthDayPattern)

   End Sub 'PrintPattern 

End Class 'SamplesDTFI
