String.Format with C#

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

 

Double

[code:c#]
</p>
<p>
//&amp;nbsp;just two decimal places<br />
String.Format("{0:0.00}", 123.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.46"<br />
String.Format("{0:0.00}", 123.4);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.40"<br />
String.Format("{0:0.00}", 123.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.00"
</p>
<p>
// max. two decimal places<br />
String.Format("{0:0.##}", 123.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.46"<br />
String.Format("{0:0.##}", 123.4);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.4"<br />
String.Format("{0:0.##}", 123.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123"
</p>
<p>
// at least two digits before decimal point<br />
String.Format("{0:00.0}", 123.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "123.5"<br />
String.Format("{0:00.0}", 23.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "23.5"<br />
String.Format("{0:00.0}", 3.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "03.5"<br />
String.Format("{0:00.0}", -3.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "-03.5"
</p>
<p>
String.Format("{0:0,0.0}", 12345.67);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "12,345.7"<br />
String.Format("{0:0,0}", 12345.67);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "12,346"
</p>
<p>
String.Format("{0:0.0}", 0.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "0.0"<br />
String.Format("{0:0.#}", 0.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "0"<br />
String.Format("{0:#.0}", 0.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // ".0"<br />
String.Format("{0:#.#}", 0.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // ""
</p>
<p>
String.Format("{0,10:0.0}", 123.4567);&amp;nbsp;&amp;nbsp;&amp;nbsp; // "&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; 123.5"<br />
String.Format("{0,-10:0.0}", 123.4567);&amp;nbsp;&amp;nbsp; // "123.5&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; "<br />
String.Format("{0,10:0.0}", -123.4567);&amp;nbsp;&amp;nbsp; // "&amp;nbsp;&amp;nbsp;&amp;nbsp; -123.5"<br />
String.Format("{0,-10:0.0}", -123.4567);&amp;nbsp; // "-123.5&amp;nbsp;&amp;nbsp;&amp;nbsp; "
</p>
<p>
String.Format("{0:0.00;minus 0.00;zero}", 123.4567);&amp;nbsp;&amp;nbsp; // "123.46"<br />
String.Format("{0:0.00;minus 0.00;zero}", -123.4567);&amp;nbsp; // "minus 123.46"<br />
String.Format("{0:0.00;minus 0.00;zero}", 0.0);&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp;&amp;nbsp; // "zero"
</p>
