Public Property AMDesignator As String

Property Value

String

The string designator for hours that are ante meridiem. The default for InvariantInfo is "AM".

Exceptions

ArgumentNullException

The property is being set to null.

InvalidOperationException

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

Remarks

The AMDesignator property is used for all times from 0:00:00 (midnight) to 11:59:59.999.

If a custom format string includes the "tt" format specifier and the time is before noon, the DateTime.ToString or ToString method includes the value of the AMDesignator property in place of "tt" in the result string. If the custom format string includes the "t" custom format specifier, only the first character of the AMDesignator property value is included. You should use "tt" for languages for which it is necessary to maintain the distinction between A.M. and P.M. An example is Japanese, in which the A.M. and P.M. designators differ in the second character instead of the first character.

For cultures that do not use an A.M. designator, this property returns an empty string.
