Initializing Array Elements    int[] myIntArray = new int[5] { 2, 4, 6, 8, 10 }; // longer syntax    int[] myIntArray = { 2, 4, 6, 8, 10 };                      // shorter syntax

定義2行3列的int 類型的數組

int [ , ] myRectangularArray = new int[2,3];

The params  keyword allows you to pass in a variable number of parameters without necessarily explicitly creating the array. 

初始化4行3列的int 類型的數組

           

const int rows = 4;    const int columns = 3;            // imply a 4x3 array            int[,] rectangularArray =           {                    {0,1,2}, {3,4,5}, {6,7,8}, {9,10,11}           };            for (int i = 0; i < rows; i++)            {                for (int j = 0; j < columns; j++)                {                    Console.WriteLine("rectangularArray[{0},{1}] = {2}",                        i, j, rectangularArray[i, j]);                }            }
