split怎么用

Question

如String a = "1234";想变成int [0] = 1 ;int [1] = 2 ;int [2] = 3 ;int [3] = 4 ;注意a = "1234" 1234之间什么都没有

Answer 1

   string a = "1234";
        char[] numbers = a.ToCharArray();
        int[] numbs = numbers.Length;
        for (int i = 0; i < numbs.Length; i++)
        {
            numbs[i] = int.Parse(numbers[i]);
        }

Answer 2

int.Parse(a[0]);这个最好
