| InvalidOperationException | The DateTimeFormatInfo object is read-only. |
Remarks
If a custom format string includes the format specifier "tt" and the time is before noon, DateTime..::.ToString returns the value of AMDesignator in place of "tt" in the format string. If the custom format string includes the format specifier "t", only the first character of AMDesignator 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 an AM designator, this property returns an empty string.
The AMDesignator property is used for all times from 00:00:00 (midnight) to 11:59:59.999.
