DateTimeFormatInfo.AMDesignator Property

Gets or sets the string designator for hours that are "ante meridiem" (before noon).

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

public string AMDesignator { get; set; }
/** @property */
public String get_AMDesignator ()

/** @property */
public void set_AMDesignator (String value)

public function get AMDesignator () : String

public function set AMDesignator (value : String)

Not applicable.

Property Value

The string designator for hours that are "ante meridiem" (before noon). The default for InvariantInfo is "AM".

Exception typeCondition

ArgumentNullException

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

InvalidOperationException

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

If the custom pattern includes the format pattern "tt" and the time is before noon, DateTime.ToString displays the value of AMDesignator in place of the "tt" in the format pattern. If the custom pattern includes the format pattern "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.
