このプログラムは、次の割り当てに対応しています。
「Sum()任意の数の整数パラメータを受け取り、それらの合計を表示するという名前のメソッドを作成します。1、3、5、または 10 個の整数の配列を渡したときにメソッドが正しく機能するMain()ことを示すメソッドを作成します。プログラムを として保存します。」Sum()UsingSum.cs

「//step 1:」部分のコードで CS0019 エラーが発生します。このエラーは、タイプboolおよびのオペランドには適用できないことを示していますint。
このコードには他にも問題があるのではないかと強く思っていますが、4 時間前に比べて大幅に改善されています…
