Developing .NET Enterprise Applications
This appendix shows you the string format specifiers you can use when developing enterprise applications using C#.
Formatting Numbers
A format specifier can quickly convert a numerical value into a properly formatted value string:
int i = 15; Console.WriteLine( "{0:c} [" + string.Format( "{0:c}", i ) + "]" );
Table C-1 describes how to format numbers that take an integer value of 15.
