I need to develop a function in c# to validate some customized formats (not the native ones). In order to do that I need to analyse char by char of the value that I am getting to find out if it is in the correct format.

The values that I will get could be something like:

1.00020
4.00155001
6.000000
5.10000000000
0.00000000000000

However I am struggling to convert those numbers to string keeping the same shape. I can't really use the formats provided by the framework because I don't know how many decimals places the value that I will get has.

To get around of this I tried to use (BitConverter.GetBytes(decimal.GetBits((decimal)valueCheck)[3])[2]) to find out the number of decimal places and then use .ToString("Format"), however it does not consider 0's at the end.

The question is simple: How can I convert a double to string in order to always keep exactly the same number and decimal places when I don't know how many decimal places my input has?

Why don't you get them as string at first? – Mohsen Kamrani Sep 20 '16 at 02:26

@mok If I convert it to string at first, I will not keep trailing 0s. – LeoPinheiro Sep 20 '16 at 05:20
