Converts the value of the current DateTime object to its equivalent long date string representation.

Assembly:  mscorlib (in mscorlib.dll)

Public Function ToLongDateString As String

Return Value

Type: System.String

A string that contains the long date string representation of the current DateTime object.

The value of the current DateTime object is formatted using the pattern defined by the LongDatePattern property associated with the current thread culture. The return value is identical to the value returned by specifying the "D" standard DateTime format string with the ToString(String) method.


The string returned by the ToLongDateString method is culture-sensitive. It reflects the pattern defined by the current culture's DateTimeFormatInfo object. For example, for the en-US culture, the standard long date pattern is "dddd, MMMMdd, yyyy"; for the de-DE culture, it is "dddd, d. MMMMyyyy"; for the ja-JP culture, it is "yyyy'?'M'?'d'?'". The specific format string on a particular computer can also be customized so that it differs from the standard long date format string.

For more information about the current thread culture, see the CurrentCulture property. For more information about format characters, format patterns, and the output they produce, see the Formatting Types in the .NET Framework topic. For more information about changing the format pattern associated with a format character, see the DateTimeFormatInfo class.

The following example demonstrates the ToLongDateString method.

        Console.WriteLine("Short date pattern: ""{0}""", ci.DateTimeFormat.ShortDatePattern)
        Console.WriteLine("Short date string:  ""{0}" & vbCrLf, myDateTime.ToShortDateString())

        ' Display the short time pattern and string.
        Console.WriteLine("Short time pattern: ""{0}""", ci.DateTimeFormat.ShortTimePattern)
        Console.WriteLine("Short time string:  ""{0}" & vbCrLf, myDateTime.ToShortTimeString())

'This code example produces the following results:

'object associated with the current thread culture.
'Current culture: "en-US"

'Short date pattern: "M/d/yyyy"
'Short date string:  "5/16/2001"
'Short time pattern: "h:mm tt"
'Short time string:  "3:02 AM"
