[C#] 多次元配列を確保する – 端くれプログラマの備忘録

多次元配列の確保する方法。

配列の確保

int[,] array = new int[4, 2];

int[, ,] array1 = new int[4, 2, 3];

int[,] array = new int[4, 2];

int[, ,] array1 = new int[4, 2, 3];

配列の初期化

{
    { 1, 2 },

    { 7, 8 }
};

// A similar array with string elements.

{
    { "one", "two" },
    { "three", "four" },
    { "five", "six" }
