How can I reformat a string to exclude leading zeros?

I have strings like this:

开发者_如何学Pythonvar abc = "002";
var def = "023";

How can I easily change the strings so the leading zeros are dropped?

Take a look at TrimStart:

numberString = numberString.TrimStart('0');

From MSDN:

The TrimStart method removes from the current string all leading characters that are in the trimChars parameter. The trim operation stops when a character that is not in trimChars is encountered.

The easiest correct way is:

int.Parse(s).ToString();

The trim methods all fail for inputs of "0000", they'll return an empty string instead of the correct "0".

If this is always with int, you can just parse it:

abc = int.Parse(abc).ToString()

var str = int.Parse(abc).ToString(); should do the work I think. Convert number to int, and then just convert it back to string.

var abc = "0023";
var zeroless = abc.TrimStart('0');

output: "23"

        string some_string = "000045";
        string ur_desire = int.Parse(some_string).ToString();
        Console.WriteLine(ur_desire);

thix ix the good answer i think because it also works with negative number..
