に複数の値がマップされているコンソール プログラムを作成していdictionary keyLookupます。キーを使用していくつかを出力するifコマンドを使用していますconsole.writeline = ("stuff");が、値とキーが同じ（辞書内）の場合にのみ機能します。これがなぜなのかわかりません。私は何を間違えたのかを理解しようとしていくつかの変数をいじっていlistましforeachたが、今でも機能し続けているにもかかわらず、私が望むようには機能しません。
またconsole.readline();、自分の辞書にない単語があると、すべてがクラッシュします。これは私が望んでいないことであり、ある時点でそうしなかったのと同じように、なぜそれを行ったのかわかりません。また、私のmathFunction辞書は、私の辞書が機能するように機能しkeyLookupます。違いは、リストを使用して相互参照する方法にあると思いますがkeyLookup。
