String.Format an integer to use a thousands separator without decimal places or leading 0 for small integers
Silly question, I want to format an integer so that it appears with the 1000's separator (,), but also without decimal places and without a leading 0.
My attempts so far have been:
String.Format("{0} {1}", 5, 5000); // 5 5000
String.Format("{0:n} {1:n}", 5, 5000); // 5.00 5,000.00
String.Format("{0:0,0} {1:0,0}", 5, 5000); // 0开发者_运维问答5 5,000
The output I'm after is:
5 5,000
Is there something obvious that I'm missing?
This worked for me.
String.Format("{0:#,0} {1:#,0}", 5, 5000); // 5 5,000
Try this:-
String.Format("{0:n0}",5000) // 5,000
String.Format("{0:n0}",5) // 5
String.Format("{0:n0}",0) // 0
String.Format("{0:#,0} {1:#,0}", 5, 5000); // "5 5,000"
0
in a format string means put the digit that belongs here, or else a [leading/trailing] zero [to make things align, etc.]. EDIT: You'll definitely want one as the last digit in the pattern, or a zero value will be rendered as an empty String#
means don't put anything into the output unless there's a significant digit here.
EDIT (thanks @eulerfx):
- the last portion needs to be a
0
rather than a#
(as I initially had it) as a value of zero would otherwise be rendered as a zero-length string.
Try
String.Format("{0:#,#}", 4000);
This also works:
40000.ToString("#,#")
