using System; public class Test { public static char[,] pHone = {{ 'a','b','c',' '},{'d','e','f',' '},{'g','h','i',' '},{'j','k','l',' '},{'m','n','o',' '},{'p','q','r','s'},{'t','u','v',' '},{'w','x','y','z'}}; public static void Main() { // your code goes here for (int i = 0; i < pHone.GetLength(1); i++) { if (i != 0) Console.Write(","); Console.Write(pHone[0, i]); } Console.WriteLine(); } }
a,b,c,
去掉空格
using System; public class Test { public static char[,] pHone = {{ 'a','b','c',' '},{'d','e','f',' '},{'g','h','i',' '},{'j','k','l',' '},{'m','n','o',' '},{'p','q','r','s'},{'t','u','v',' '},{'w','x','y','z'}}; public static void Main() { // your code goes here bool first = true; for (int i = 0; i < pHone.GetLength(1); i++) { if (pHone[0, i] != ' ') { if (!first) Console.Write(","); else first = false; Console.Write(pHone[0, i]); } } Console.WriteLine(); } }
a,b,c
