<lang csharp>string s = "12345";
s = (int.Parse(s) + 1).ToString();
// The above functions properly for strings >= Int32.MinValue and
// < Int32.MaxValue. ( -2147483648 to 2147483646 )
// The following will work for any arbitrary-length integer string.
// (Assuming that the string fits in memory, leaving enough space
// for the temporary BigInteger created, plus the resulting string):

bis = (BigInteger.Parse(bis) + 1).ToString();
// Note that extremely long strings will take a long time to parse
// and convert from a BigInteger back into a string.</lang>
