Answer 1

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.
