私はSortRetardedStudentsを呼び出そうが、何でも、私は常にエラーが発生しません。この私のコード。私は安全でないものを使用しようとしました。プロジェクトにはプロパティを追加して、安全でないコードを実行できるようにしました。 現在、私のエラーはCS0208

問題の解決に役立ちます。私はポインタとビデオ後の参照evemを理解することが非常に悪いです。

Answer 1

安全でないコードを使用する理由はありません。 原産地コードにstaticが足りないようです。

public static void SortRetardedStudents(RetardedStudent[] Retards)
