c# の別の Windows アプリケーションでコンソール アプリケーション exe (c# で開発) を実行しています。
Process p = Process.Start("strExePath");
私が実行したコンソール アプリケーションは、いくつかのユーザー入力を想定しており、コンソール exe ファイルを実行する Windows アプリケーションの C# コードによってそれらのユーザー入力を提供したいと考えています。どうすればこれを達成できますか？

経由で起動したコンソール アプリケーションの標準入力をリダイレクトできますProcess.Start()。
そのためには、 を使用する必要がありますProcessStartInfo.RedirectStandardInput。
リンクした MSDN ドキュメントに完全な例があります。
また、これはおそらくニーズに合わせて調整できるラッパー クラスです。(コードはやや古いため、 などの最新の C# 機能を使用していませんTasksが、何をする必要があるかがまだ示されていることを願っています。)
入力と出力の両方をリダイレクトする場合にデッドロックなしで I/O リダイレクトを機能させるには、別のスレッドを使用して I/O を処理する必要があることに注意してください。
