Is converting Integer to five digit Binary in c# possible?

Question

I found some answers on converting decimal to binary and I made this code and its working fine,

int number = 2;
string binary = Convert.ToString(number, 2); // gives 10 as binary

But what I want is 00010 as five digit no.

And I am not looking to convert into HEX,

How do I get that?

It might be a duplicate but not of [the current duplicate](https://stackoverflow.com/questions/4416974/convert-10-digit-number-to-hex-string) selected. I didn't find any standard numeric format string that converts the number to it's binary representation. — Zohar Peled, Jan 23 '18 at 14:20

Use PadLeft:

var binary = Convert.ToString(number, 2).PadLeft(5, '0');

See a live demo on rextester.

fast solution :

int number = 2;
string binary = Convert.ToString(number, 2); // gives 10 as binary
if (binary.Length < 5) binary = new String('0',5- binary.Length ) + binary;

output : 00010
