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:(###) ###-####}",18005551212);

This will output "(800) 555-1212".
