二维数组的应用：
案例1：成绩表：
static void Main(string[] args) { int i, j; int[,] a = new int[3, 4]; for (i = 0; i < 3; i++) { a[i, 0] = i + 1; Console.Write("第"+(i+1)+"位同学的语文成绩为"); a[i, 1] = Convert.ToInt32(Console.ReadLine()); Console.Write("第" + (i + 1) + "位同学的数学成绩为"); a[i, 2] = Convert.ToInt32(Console.ReadLine()); a[i, 3] = a[i, 1] + a[i, 2]; } Console.Clear(); Console.Write("学号\t语文\t数学\t总分"); Console.WriteLine(); for (i = 0; i < 3;i++ ) { for (j = 0; j < 4; j++) { Console.Write(a[i, j] + "\t"); } Console.WriteLine(); } }

案例2：推箱子
