本文采用冒泡排序法对二维数组进行排序

代码内容如下

using System; namespace experment4 { class Program { private static int result; private static int result1; static void Main(string[] args) { string[,] a = new String[5,2];             a[0, 0] = "2"; a[0, 1] = "Smith";             a[1, 0] = "4"; a[1, 1] = "John";             a[2, 0] = "5"; a[2, 1] = "Mary";             a[3, 0] = "1"; a[3, 1] = "Cherr";             a[4, 0] = "3"; a[4, 1] = "Tom";             Console.WriteLine("排序前：");             Console.Write("学号："); for(int i = 0; i < 5; i++) {                 Console.Write(a[i, 0].ToString().PadRight(8,' ')); }             Console.WriteLine();             Console.Write("姓名："); for(int j = 0; j < 5; j++) {                 Console.Write(a[j, 1].ToString().PadRight(8, ' ')); }             Console.WriteLine(); //按学号排序             Console.WriteLine("按学号排序后："); for (int i = 0; i < 5; i++) { for (int j = 0; j < 5 - i; j++) { if(j!=4-i)                      result = string.Compare(a[j , 0], a[j+1,0],true); if (j!=4-i&&result >0) { string temp = a[j, 0];                         a[j, 0] = a[j + 1, 0];                         a[j + 1, 0] = temp; string temp2 = a[j, 1];                         a[j, 1] = a[j + 1, 1];                         a[j + 1, 1] = temp2; } } }             Console.Write("学号："); for (int i = 0; i < 5; i++) {                  Console.Write(a[i, 0].ToString().PadRight(8, ' ')); }             Console.WriteLine();             Console.Write("姓名："); for (int i = 0; i < 5; i++) {                  Console.Write(a[i, 1].ToString().PadRight(8, ' ')); }             Console.WriteLine(); //按姓名排序             Console.WriteLine("按姓名排序后：");             Console.WriteLine(); for (int i = 0; i < 5; i++) { for (int j = 0; j < 5 - i; j++) { if (j != 4 - i)                         result1 = string.CompareOrdinal(a[j, 1], a[j + 1, 1]); if (j != 4 - i && result1 >= 1) { string temp = a[j, 1];                         a[j, 1] = a[j + 1, 1];                         a[j + 1, 1] = temp; string temp2 = a[j, 0];                         a[j, 0] = a[j + 1, 0];                         a[j + 1, 0] = temp2; } } }             Console.Write("学号："); for (int i = 0; i < 5; i++) {                  Console.Write(a[i, 0].ToString().PadRight(8, ' ')); }             Console.WriteLine();             Console.Write("姓名："); for (int i = 0; i < 5; i++) {                  Console.Write(a[i, 1].ToString().PadRight(8, ' ')); }             Console.WriteLine(); } } }
