Property Value

Type: System.String
The custom format string for a month and day value.

ExceptionCondition
ArgumentNullException

The property is being set to a null reference (Nothing in Visual Basic).

InvalidOperationException

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.
