How to display a number close to zero in c#?

I have a problem. I have a double number like 0.00000001. Then I should convert it into String and put it in textbox (Convert.ToString(0.00000001)). But that number displayed like 1E-08. Math.Round is not working here. I should display that number like 0.00000 (at least), not just 0.

You can use The numeric ("N") format specifier for that;

(0.00000001).ToString("N5").Dump(); // 0,00000
(0.00000001).ToString("N6").Dump(); // 0,000000
(0.00000001).ToString("N8").Dump(); // 0,00000001

Since my CurrentCulture's NumberDecimalSeparator is ,, it represents it as 0,0 not 0.0. If it is the same for you, you can use InvariantCulture as a second parameter in your .ToString() method.
