Without any error checking you can do:

var value = "231143";
var array = value.Select(c => c - '0').ToArray();

This makes use of a trick whereby you can subtract '0' from the value of a single character holding a number to get its integer value.

Note that this solution is only correct if it is guranteed that the input string only contains digits
@Ackdari I think we can safely assume this given by the wording of the question.
