It's simple that if you want to show a number as exactly as what it looks, we can cast it to decimal and use the default ToString() like this:

var s = ((decimal)yourNumber).ToString();
//if yourNumber = 0.00000000000000000000000006
//just append the M after it:
var s = (0.00000000000000000000000006M).ToString();

Try with the Roundtrip 'R' format specifier:

double a = 0.000006;
string resultString = a.ToString("R");

Please check this article and find the format which suits your needs: http://www.csharp-examples.net/string-format-double/

Looks like this one is good enough:

String.Format("{0:0.00}", 123.4567);

Use String.Format() with the format specifier.

double a = 0.000006;
string formatted = String.Format("{0:F6}", a);
