c# int[] 和string[] 之间的相互转换

1、int [] 转换为 string []

int[] input= new int[10] { 1, 6, 3, 5, 8, 2, 9, 0, 4, 7 }; 

string[] output = Array.ConvertAll<int, string>(input, delegate(int s) { return s.ToString(); });

//ConvertAll<TInput, TOutput>(TInput[] array, Converter<TInput, TOutput> converter);

string outStr=string.Join(",", output);

2、string[] 转换为 int[]

string[] input =new  int[10]{"1", "6", "3", "5", "8", "2", "9", "0", "4", "7"};

int [] output=Array.ConvertAll<string, int>(input, delegate(string s) { return int.parse(s); });
