C#のメモ帳 動的に配列の要素数を増やす

Last updated at Posted at 2017-09-15
動的に配列の要素数を増やすぞ!
string[] 顧客 = new string[0];   //空の配列を作る。

 for(int i= 0; i < 9; i++)
{
    Array.Resize(ref 顧客, i + 1);  //配列のリサイズ。既存値はそのまま。リサイズ直後の値はNull(のようだ)。
    顧客[i] = i;
    Console.WriteLine(顧客[i]);
}

Console.WriteLine("要素数: "+ 顧客.length);
