pictureBox の配列
c#のフォームアプリケーションで PictureBox を配列として扱いたい
出来れば、.cs[デザイン]の方で設定してしまいたい
最近C#フォームアプリケーションの勉強を始めました。
今 vs2022 で反射神経を測るゲームを作ろうとしています。
そこで pictureBox を縦横 (4,4) 計16個用意し、timer で一定時間毎にランダムな pictureBox をオン（pictureBoxを指定色で塗りつぶし、ストップウォッチを起動した状態) にし、オンになった pictureBox がクリックされたらストップウォッチの時間を合計反応時間に加算して停止、制限時間後に平均反応時間を算出して表示しようとしています。
これを作るにあたり、作った pictureBox0 から pictureBox15 を扱う際、いちいちswitch文で16個の分岐を作ると冗長で分かりづらいので、これを pictureBox[16] のような配列にして
pictureBox[i].Image = onBmp
// onBmpは指定色で塗りつぶしたBitmap
などのようにして様々な処理したいです。
しかし .cs[デザイン] の方では pictureBox の配列を作る項目が見つからず、ネットで調べてみてもしっくりくる記事が見当たらず、これをどうしようか悩んでいます。
そこで質問です。
Q1.
.cs[デザイン] で pictureBox の配列を作る方法はあるのか。
Q2.
Q1 が出来ないならソースコードの方に記述して pictureBox の配列を作れるのか。
（追記）自己解決しました。普通にPictureBox[] pictureBoxs = new pictureBoxs[16]; で宣言したら使えるみたいですね。
（追記）質問追加します。
Q2.1.
Q2ができる場合、ソースコードの方で宣言した pictureBox の配列を .cs[デザイン]の方でいじる方法はあるか。
Q3.
Q2 が出来るなら、.cs[デザイン]の方で用意した pictureBox[0] ~ pictureBox[15] に pictureBox0 ~ pictureBox15 を代入して
int* ints[10]
int int0 = 0;
// 1 ~ 8
int int9 = 9;
ints[0] = &int0;
// 1 ~ 8
ints[9] = &int9;
for ( int i = 0; i < 10; i++ ) {
printf(" %d", int[i]);
}
// 実行結果
// 0 1 2 3 4 5 6 7 8 9
というcのアドレスを使ったような実装方法は可能なのか。
Q4.
Q3が不可能な場合、考えられる中で一番スマートな実装方法を教えていただきたいです。
質問内容としては以上です。お答えいただければ幸いです。よろしくお願いいたします。
ソースコード
以下のソースコードは実装途中です。
Startボタンを押したらTimerが起動する代わりに、Box0がオンになります。
