Public Property PMDesignator As String

Property Value

Type: System.String
The string designator for hours that are "post meridiem" (after noon). The default for InvariantInfo is "PM".


An attempt was made to set the property to Nothing.


The DateTimeFormatInfo object is read-only.

If a custom date and time format string includes the "tt" format specifier and the time is after noon, DateTime.ToString returns the value of PMDesignator in place of "tt" in the custom format string. If the custom format string includes the "t" custom format specifier, only the first character of PMDesignator is displayed. Your application should use "tt" for languages for which it is necessary to maintain the distinction between AM and PM. An example is Japanese, for which the AM and PM designators differ in the second character instead of the first character.

For cultures that do not use a PM designator, this property returns an empty string.

The PMDesignator property is used for all times from 12:00:00 (noon) to 23:59:59.999.
