[雑記] 非同期制御フロー
概要 C# 5.0のasync/awaitがなかったころ、少し複雑目な非同期制御フローをどうやって実現していたかという話。 C# 5.0を使えない状況下で非同期処理を書くことになった場合の参考としてや、async/awaitがどうやって実現されているかを知るきっかけになると思います。 サンプル コード（ZIP 形式。proj/sln 含め一式。） ポイント C# 5.0（await演算子）便利だなー await演算子が内部的にやっていることは、イテレーターに近い なので、昔はイテレーターを使って非同期処理をすることが結構あった サンプルの要件 今回の例として使うのは、Figure 1に示すような、確認ダイアログ表示のフロー。 確認ダイアログを表示する例 要は、何かを実行するにあたって、特定条件下では確認ダイアログの表示が必要で、すべてのダイアログで「OK」を押したときにだけ実行に移るという

Async in 4.5: Worth the Await - .NET Blog
Developers often ask for guidance on how to write responsive user interfaces. Reading most books about the .NET Framework over the past ten years, you’ll see coverage of the asynchronous programming model which requires a lot of careful attention while coding. That’s why the async features in the latest versions of C# and Visual Basic are tremendous step forward. And language innovation like async

イベント・プログラミングとRx（1/3） - ＠IT
本連載の第1回では、Reactive Extensions（以降、Rx）の概要とインストール方法を解説した。今回からは具体的な使い方を見ていこう。 まずはRxを利用する際の基本的な流れを見ていく。次に、Rxの持つ代表的な2つの性質であるイベントと非同期のうち、イベントを中心的に取り上げる。 ●基本的な記述方法 最初に、シンプルなRx（Observableオブジェクト）のコードと、foreach文（Enumerableオブジェクト）のコードの対比を見てみよう。 using System.Linq; using System.Reactive.Linq; // Observableオブジェクト（Rxのコード） Observable.Range(1, 5) .Subscribe(x => Console.WriteLine(x)); // Enumerableオブジェクト foreach (va
Reactive Extensionsの概要と利用方法
連載：Reactive Extensions（Rx）入門 第1回 Reactive Extensionsの概要と利用方法 河合 宜文 2011/11/01 C# 3.0より導入され、プログラミング・スタイルに大きな変革をもたらしたLINQはご存じだろうか。詳しくは「特集：Road to LINQ」で紹介されているが、データ加工における処理の手間を大きく解消するものである。LINQの特徴として、各種のデータソース（＝配列やXMLデータ、SQLデータベースなど）に対して統一的な記法を提供することが挙げられる。 Reactive Extensions（以降、Rx）は、LINQが適用できるデータソースの概念を「非同期」と「イベント」に広げた、いわば「LINQ to Asynchronous」「LINQ to Events」とでも言うべきものである。それにより、従来では手間のかかった複雑な非同期処理
