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

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

Answer 2

int.Parse(a[0]);这个最好
