StrftimeParser

StrftimeParser is a .NET Standard 2.0 library that allows you to work with C-style strftime/strptime string formats within .NET.

The project provides a main class called Strftime that exposes a static method Parse, and a static method ToString.

The Parse method is the equivalent of the strptime in time.h of C language, as it allows to obtain a DateTime object given a format specifier and a formatted date string.

The ToString method is the equivalent of the strftime in time.h of C language, as it allows to obtain a formatted date string, given a format specifier and a DateTime object

Usage

To use StrftimeParser in your .NET project, follow these simple steps:

1. Add the NuGet package StrftimeParser to your .NET project.

2. Import the StrftimeParser namespace in your code file.

3. Now call the Parse or the ToString method

Here an example of Parse:

using StrftimeParser;

string strftimeString = "2001-08-23 14:55:02";
string formatSpecifier = "%Y-%m-%d %H:%M:%S";

DateTime dateTime = Strftime.Parse(strftimeString, formatSpecifier);

// dateTime now contains the formatted date as a .NET DateTime object

Here an example of ToString:

using StrftimeParser;

var dt = new DateTime(1970, 1, 2, 3, 4, 5);
var format = "%c";

var res = Strftime.ToString(dt, format);

// res now contains the formatted date string

How to use a specified CultureInfo when parsing

To execute the parsing with a specific Culture, you can pass a CultureInfo instance to the Parse method:

DateTime dateTime = Strftime.Parse(strftimeString, formatSpecifier, CultureInfo.GetCultureInfo("it-IT"));

// dateTime now contains the formatted date as a .NET DateTime object

How to use a specified CultureInfo when converting to string

To execute the parsing with a specific Culture, you can pass a CultureInfo instance to the ToString method:

var result = Strftime.ToString(dt, formatSpecifier, CultureInfo.GetCultureInfo("it-IT"));

// result now contains the formatted string

Compatibility

At the moment, StrftimeParser supports these format specifiers:

• %a - Abbreviated weekday name *
• %A - Full weekday name *
• %b - Abbreviated month name *
• %B - Full month name *
• %d - Day of the month as a zero-padded number
• %D - Short MM/DD/YY date, equivalent to %m/%d/%y
• %e - Day of the month as a space-padded number
• %F - Short YYYY-MM-DD date, equivalent to %Y-%m-%d
• %c - Date and time representation
• %I - Hour in 12h format (01-12)
• %p - AM or PM designation
• %H - Hour in 24h format (00-23)
• %j - Day of the year (001-366)
• %m - Month as a decimal number (01-12)
• %M - Minute (00-59)
• %n - New-line character ('\n')
• %t - Horizontal-tab character ('\t')
• %S - Second (00-61)
• %T - ISO 8601 time format (HH:MM:SS), equivalent to %H:%M:%S
• %u - ISO 8601 weekday as number with Monday as 1 (1-7)
• %w - Weekday as a decimal number with Sunday as 0 (0-6)
• %y - Year, last two digits (00-99)
• %Y - Year

* The specifiers marked with an asterisk (*) are locale-dependent.
