Formatting values

Hi i have a int example as 3 i need to format it as 003 . is the only way is convert to a st开发者_运维问答ring and concat and convert back ?

I guess this is what you want:

int n = 3;
string formatted = n.ToString("000");

Alternatively:

string formatted = String.Format("{0:000}", n);

More info here.

You can apply the .ToString("000"); method.

Debug.WriteLine(3.ToString("000"));

You can parse the resulting string value by using int.Parse or int.TryParse:

Debug.WriteLine(int.Parse("003"));

See Custom Numeric Format Strings

If it's an int object, the leading zeros will always be removed, regardless if you convert it to a string and back.

use the pad functionint i = 1; i.ToString().PadLeft(3, '0');
