DateTimeFormatInfo::DateSeparator Property

Gets or sets the string that separates the components of a date, that is, the year, month, and day.

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

property String^ DateSeparator {
	String^ get ();
	void set (String^ value);

Property Value

Type: System::String
The string that separates the components of a date, that is, the year, month, and day. The default for InvariantInfo is "/".


The property is being set to nullptr.


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

If the custom pattern includes the format pattern "/", DateTime::ToString displays the value of DateSeparator in place of the "/" in the format pattern.

The date separator is derived from the ShortDatePattern property. Your applications are recommended to set the short date pattern to the exact value of interest, instead of attempting to have the date separator replaced. For example, to obtain the pattern MM-DD-yyyy, the application should set "MM-DD-yyyy" specifically. This also permits the setting of patterns such as "MM/DD, yyyy" that don't contain a traditional separator between all parts of the format.
