How to convert an integer to its string representation adding padding zeros

Question

int num = 00;
string s=num.ToString();

It is giving value "0". The expected result is "00". How to do this?

Can anyone Help me?

Are you expecting `int num = 00;` and `int num = 0;` to do different things? If you are, you're going to be disappointed. — Jon Skeet, May 15 '17 at 16:19

It's in your value assignment. An int of 00 always has value 0. If you want to always show two digits, you need to apply a format to your ToString() call

int num = 00;
string s= num.ToString("D2");

That should do the trick.

You can achieve the desired result using the implementation of the ToString() method passing a parameter "D2" as shown in the demo link: http://rextester.com/JKIDK14711 Or you can get more information about the parameters that ToString() accepts from here: https://msdn.microsoft.com/en-us/library/dwhawy9k(v=vs.110).aspx
