How to force a sign when formatting an Int in c#

Question

I want to format an integer i (-100 < i < 100), such that:

-99 formats as \"-99\"
9 formats as \"+09\"
-1 formats as \"-01\"
0 forma

Answer 1

You might be able to do it with a format string like so..

i.ToString("+00;-00");

This would produce the following output..

2.ToString("+00;-00");    // +02
(-2).ToString("+00;-00"); // -02
0.ToString("+00;-00");    // +00

Take a look at the MSDN documentation for Custom Numeric Format Strings
