Format specifiers

Format specifiers are used to state a desired format when formatting object values.

In ERP.net, they can be used as a second parameter for the calculated attribute operator FORMATSTRING or in the formatting string (‘:FormatSpecifier’) when referencing domain attributes in the SENDMAIL action (‘{DomainAttribute:FormatSpecifier}’).

There are two main types of format specifiers:

• standard .Net format specifiers (Numeric, Date - Time, etc.)
• custom format specifiers (Multilanguge string, Custom property)

Standard .Net format specifiers

The list below contains the most frequently used .Net format specifiers.

For a complete list and more information, please look at the official .Net documentation site here: https://learn.microsoft.com/en-us/dotnet/standard/base-types/standard-numeric-format-strings#standard-format-specifiers

Numeric format specifiers

• 'C', 'c' - abbreviation for Currency.

Converts a number to a string that represents a currency amount. Can be used with a precision specifier that indicates the desired number of digits after the decimal point. The decimal symbol separator and the currency symbol depend on the local regional settings.

Returns:

123.4656 ('C') → $123.46

123.4656 ('C3') → $123.466

• 'D', 'd' - abbreviation for Decimal.

Converts a number to a string of decimal digits (0-9), prefixed by a minus sign if the number is negative. Can be used with a precision specifier that indicates the desired number of digits after the decimal point. This format is supported only for integral types.

Returns:

1234 ('D') → 1234

1234 ('D6') → -001234

• 'N', 'n' - abbreviation for Number.

Converts a number to a string. Can be used with a precision specifier that indicates the desired number of digits after the decimal point. The decimal symbol separator depends on the local regional settings.

Returns:

123.4656 (N) → 123.47

123.4656 (N3) → 123.466

• 'P', 'p' - abbreviation for Percent.

Multiplies a number by 100 and converts it to a string representing a percentage. The precision specifier shows the desired number of decimal places. The decimal symbol separator depends on the regional settings.

Returns:

0.488869 (P) → 48.89%

0.488869 (P3) → 48.887%

Date and time format strings

In order to define the text representation of a date and time value, standard date-and-time format specifiers can be used alone, as standard date-and-time format string, or in combination, as custom format string.

A standard date-and-time format string uses a single format specifier. Any date and time format string that contains more than one character, including white space, is interpreted as a custom format string.

Standard date and time format strings:

• 'D', 'd' - Short date pattern.

The returned format depends on the pattern set for Short date in the local regional settings.

Returns:

2019-05-10 15:18:39.013 → 10.5.2019

• 'D' - Long date pattern.

The returned format depends on the pattern set for Long date in the local regional settings.

Returns:

2019-05-10 15:18:39.013 → 10 May 2019

• 'f' - Full date/time pattern (short time).

The returned format depends on the pattern set for Long date and Short time in the local regional settings.

Returns:

2019-05-10 15:18:39.013 → 10 May 2019 5:18

• 'F' - Full date/time pattern (long time).

The returned format depends on the pattern set for Long date and Short time in the local regional settings.

Returns:

2019-05-10 15:18:39.013 → 10 May 2019 5:18:39

• 'M', 'm' - Month/day pattern.

The returned format depends on the current culture set in the local regional settings.

Returns:

2019-05-10 15:18:39.013 → May 10

• 'u' - Universal sortable date/time pattern.

Returns:

2019-05-10 15:18:39.013 → 2019-05-10 15:18:39Z

• 'U' - Universal full date/time pattern.

Returns:

2019-05-10 15:18:39.013 → 10 May 2019 5:18:39

Custom format specifiers

There are also custom format specifiers created specifically for ERP.net.

They're different for the different data types and are described below.

Multilanguge string

• 'C', 'CURRENT' - returns the string of the current value.

• 'D', 'DUMP' - returns the content of the multilanguage string in the format:

EN=<english-string> DE=<german-string>

• 'T', 'TRANSLITERATED' - returns transliteration to the current language.

• format specifiers for a particular language - return the translation of a specified language.

If there's no transliteration set for that language, they return an empty string.

Note

Format specifiers for a particular language are supported since ERP.net version 2019.1.
