I have a huge problem with the following code:
DateTime date = DateTime.Now;
String yearmonthday = date.ToString("yyyy/MM/dd");
MessageBox.Show(yearmonthday);
the problem is, C# uses the system date separator instead of always using "/" as i specified. If I run that code, I get the following output:
2011/03/18
but if I go to "control panel" -> "regional and language options" and change the date separator to "-", I get
2011-03-18
Even if in the toString method I specified to use '/' . Am I missing something or this is a C# / .Net Framework bug?
C programming language is a machine-independent programming language that is mainly used to create many types of applications and operating systems such as Windows, and other complicated programs such as the Oracle database, Git, Python interpreter, and games and is considered a programming foundation in the process of ...
Full form of C is “COMPILE”. One thing which was missing in C language was further added to C++ that is 'the concept of CLASSES'.
C is a general-purpose language that most programmers learn before moving on to more complex languages. From Unix and Windows to Tic Tac Toe and Photoshop, several of the most commonly used applications today have been built on C. It is easy to learn because: A simple syntax with only 32 keywords.
What is C? C is a general-purpose programming language created by Dennis Ritchie at the Bell Laboratories in 1972. It is a very popular language, despite being old. C is strongly associated with UNIX, as it was developed to write the UNIX operating system.
The /
in your format string is a placeholder for the date separator -- the behaviour that you're seeing is by design and clearly documented.
If you need a literal /
then you need to escape it in your format string, which should then look something like "yyyy\/MM\/dd" or "yyyy'/'MM'/'dd".
Try like this:
String yearmonthday = date.ToString("yyyy/MM/dd", CultureInfo.InvariantCulture);
or escape the /
String yearmonthday = date.ToString(@"yyyy\/MM\/dd");
The problem is that / is reserved for the date character - so this isn't a bug - it's a feature that this gets interpreted according to the locale.
Try escpaing the / character with:
var d = DateTime.Now;
d.ToString("yy\\/mm\\/dd").Dump();
