DateTimeFormatInfo::RFC1123Pattern Property
Gets the custom format string for a time value that is based on the Internet Engineering Task Force (IETF) Request for Comments (RFC) 1123 specification.
Assembly: mscorlib (in mscorlib.dll)
Property Value
Type: System::String^The custom format string for a time value that is based on the IETF RFC 1123 specification.
The RFC1123Pattern property defines the culture-specific format of date strings that are returned by calls to the DateTime::ToString and DateTimeOffset::ToString methods and by composite format strings that are supplied the "r" and "R" standard format strings.
The RFC1123 pattern reflects a defined standard, and the property is read-only. Therefore, it is always the same, regardless of the culture. The custom format string is "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'".
The following example displays the value of RFC1123Pattern for a few cultures.
using namespace System; using namespace System::Globalization; void PrintPattern( String^ myCulture ) { CultureInfo^ MyCI = gcnew CultureInfo( myCulture,false ); DateTimeFormatInfo^ myDTFI = MyCI->DateTimeFormat; Console::WriteLine( " {0} {1}", myCulture, myDTFI->RFC1123Pattern ); } int main() { // Displays the values of the pattern properties. Console::WriteLine( " CULTURE PROPERTY VALUE" ); PrintPattern( "en-US" ); PrintPattern( "ja-JP" ); PrintPattern( "fr-FR" ); } /* This code produces the following output. CULTURE PROPERTY VALUE en-US ddd, dd MMM yyyy HH':'mm':'ss 'GMT' ja-JP ddd, dd MMM yyyy HH':'mm':'ss 'GMT' fr-FR ddd, dd MMM yyyy HH':'mm':'ss 'GMT' */
