Question

This might be really simple but i have a service that returns a string that has a number preceded with zeros. The count of zeros is not predictable but i need to extract the number out of the value. The length of the value is also not constant. For ex. 00001234, 002345667, 0000000, 011, 00000987 – in all these values, i need to extract the 1234, 2345667, <no value>, 11, 987.
i have tried doing the below code but it returns the zeros as well:

string.Join( null,System.Text.RegularExpressions.Regex.Split( expr, "[^\\d]" ) );

Can anyone help?

Got my Answer::

I got it using stringObj.TrimStart('0'). But i agree using Int.Parse or Int.TryParse is a better way of handling. Hope this is useful to someone like me!

Answer 1

int ret;

if (int.TryParse("0001234", out ret))
{
    return ret.ToString();
}

throw new Exception("eep");
