Question

How to take away fraction part while formatting decimal type in .NET? I need common syntax for both variants. Is there any gentle solution?

            decimal a = 1.22M;
            decimal b = 1.00M;

            String.Format("${0}", a); // result is $1.22
            String.Format("${0}", b); // result is $1.00, should be $1, HOW?

Answer 1

Assuming that ‘common syntax’ means that you need one solution to give both outputs, String.Format("${0:#.##}", x) does the trick. When x is 1.00M, the result will be "$1". when x is 1.22M, the result is "$1.22".
