Answer 1

String.Format("{0:0.##}", 2.50);

You can also convert it to a string and then do String.Trim( 0 ); to trim the trailing zeros off.

Answer 2

You could do it like this example shows:

String.Format("{0:0.00}", 123.4567);      // "123.46"
String.Format("{0:0.00}", 123.4);         // "123.40"
String.Format("{0:0.00}", 123.0);         // "123.00"

(基本上使用<代码>String.Format/code>功能)
