TimeZone.DaylightName Property

Gets the daylight saving time zone name.

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

public abstract string DaylightName { get; }
/** @property */
public abstract String get_DaylightName ()

public abstract function get DaylightName () : String

Not applicable.

Property Value

The daylight saving time zone name.

If daylight saving time is not used in the time zone, an empty string ("") is returned.

The DaylightName property corresponds to the System.TimeZoneInfo.DaylightName property.

The following example references and displays the DaylightName property of the current time zone.
