Question

I’m trying to produce just the day number in a WPF text block, without leading zeroes and without extra space padding (which throws off the layout). The first produces the day number with a space, the second produces the entire date. According to the docs, ‘d’ should produce the day (1-31).

string.Format('{0:d }', DateTime.Today); string.Format('{0:d}', DateTime.Today); 

UPDATE:Adding % is indeed the trick. Appropriate docs here.

Answer 1

See here

d, %d

The day of the month. Single-digit days do not have a leading zero. The application specifies ‘%d’ if the format pattern is not combined with other format patterns.

Otherwise d is interpreted as:

d – ‘ShortDatePattern’

PS. For messing around with format strings, using LinqPad is invaluable.
