String.Format with C# - PieterBrinkman.com

In this post I will add examples of String.Format or links to sites with good examples.

Double

[code:c#]


//&nbsp;just two decimal places 
String.Format("{0:0.00}", 123.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.46" 
String.Format("{0:0.00}", 123.4);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.40" 
String.Format("{0:0.00}", 123.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.00"


// max. two decimal places 
String.Format("{0:0.##}", 123.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.46" 
String.Format("{0:0.##}", 123.4);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.4" 
String.Format("{0:0.##}", 123.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123"


// at least two digits before decimal point 
String.Format("{0:00.0}", 123.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "123.5" 
String.Format("{0:00.0}", 23.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "23.5" 
String.Format("{0:00.0}", 3.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "03.5" 
String.Format("{0:00.0}", -3.4567);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "-03.5"


String.Format("{0:0,0.0}", 12345.67);&nbsp;&nbsp;&nbsp;&nbsp; // "12,345.7" 
String.Format("{0:0,0}", 12345.67);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "12,346"


String.Format("{0:0.0}", 0.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "0.0" 
String.Format("{0:0.#}", 0.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "0" 
String.Format("{0:#.0}", 0.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // ".0" 
String.Format("{0:#.#}", 0.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // ""


String.Format("{0,10:0.0}", 123.4567);&nbsp;&nbsp;&nbsp; // "&nbsp;&nbsp;&nbsp;&nbsp; 123.5" 
String.Format("{0,-10:0.0}", 123.4567);&nbsp;&nbsp; // "123.5&nbsp;&nbsp;&nbsp;&nbsp; " 
String.Format("{0,10:0.0}", -123.4567);&nbsp;&nbsp; // "&nbsp;&nbsp;&nbsp; -123.5" 
String.Format("{0,-10:0.0}", -123.4567);&nbsp; // "-123.5&nbsp;&nbsp;&nbsp; "


String.Format("{0:0.00;minus 0.00;zero}", 123.4567);&nbsp;&nbsp; // "123.46" 
String.Format("{0:0.00;minus 0.00;zero}", -123.4567);&nbsp; // "minus 123.46" 
String.Format("{0:0.00;minus 0.00;zero}", 0.0);&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; // "zero"

Integer

[code:c#]

String.Format("{0:00000}", 15); // "00015"
String.Format("{0:00000}", -15); // "-00015"

String.Format("{0,5}", 15);              // "   15"
String.Format("{0,-5}", 15);             // "15   "
String.Format("{0,5:000}", 15);          // " 015"
String.Format("{0,-5:000}", 15);         // "015 "

String.Format("{0:#;minus #}", 15); // "15"
String.Format("{0:#;minus #}", -15); // "minus 15"
String.Format("{0:#;minus #;zero}", 0); // "zero"

String.Format("{0:+### ### ### ###}", 447900123456); // "+447 900 123 456"
String.Format("{0:##-####-####}", 8958712551); // "89-5871-2551"

DateTime

[code:c#]

// create date time 2008-03-09 16:05:07.123
DateTime dt = new DateTime(2008, 3, 9, 16, 5, 7, 123);

String.Format("{0:y yy yyy yyyy}", dt); // "8 08 008 2008"   year
