C# date formatting is losing slash separators

Question

If I do this in C#:

Console.WriteLine(DateTime.Now.ToString(\"ffffd M/dd/yy\"));

I would expect output like this:

Wed 6/15/11         


        

Answer 1

The default behavior of the "/" (slash) in a format argument is to use the current's culture date separator.

To force the "/" (slash), you must precede it with a "\" (backslash).

Ex.: "yyyy\\/MM\\/dd" will always display a date like "2015/07/02" independent of the current culture in use.
