The ToString method takes a format specifier string that you can use. The characters you're likely interested in are '#' and '0'. With the former, it will tell you to keep that many digits. With the latter, you will keep that many digits and if they don't exist, a zero will be written instead.

Example...

            Console.WriteLine(Math.PI.ToString());
            Console.WriteLine(Math.PI.ToString("#.####"));
            Console.WriteLine(Math.PI.ToString("000.0000"));

Output:

3.1415926535897 9
3.1416
003.1416

Alternatively, you can use the Math.Round function to actually round the number to the number of decimal places you wish, then call ToString on the result.

            Console.WriteLine(Math.PI.ToString());
            Console.WriteLine(Math.Round(Math.PI, 2).ToString());

Output:

3.1415926535897 9
3.14
