C# String Formatting 

UPDATE: I show alternate ways to use string formats in WPF in this post:WPF String Formatting

This entry has been copied from SteveX (http://blog.stevex.net/index.php/string-formatting-in-csharp/) for my own easy reference.

The text inside the curly braces is {index[,alignment][:formatString]}. If alignment is positive, the text is right-aligned in a field the given number of spaces; if it’s negative, it’s left-aligned.

Strings

There really isn’t any formatting within a string, beyond it’s alignment. Alignment works for any argument being printed in a String.Format call.

Numbers

Basic number formatting specifiers: 

Custom number formatting:

;
Group separator
see below

The group separator is especially useful for formatting currency values which require that negative values be enclosed in parentheses. This currency formatting example at the bottom of this document makes it obvious:

Dates

Note that date formatting is especially dependant on the system’s regional settings; the example strings here are from my local locale.

The ‘U’ specifier seems broken; that string certainly isn’t sortable.

Custom date formatting:

Enumerations

Some Useful Examples

String.Format(”{0:$#,##0.00;($#,##0.00);Zero}”, value);

This will output “$1,240.00? if passed 1243.50. It will output the same format but in parentheses if the number is negative, and will output the string “Zero” if the number is zero.

String.Format(”{0:(###) ###-####}”, 8005551212);

This will output “(800) 555-1212?.
