Stopwatch クラス
メモ : このクラスは、.NET Framework version 2.0 で新しく追加されたものです。
経過時間を正確に計測するために使用できるメソッドとプロパティのセットを提供します。

構文解説Stopwatch インスタンスは、1 つの間隔の経過時間、または複数の間隔の経過時間の合計を計測できます。一般的な Stopwatch のシナリオでは、Start メソッドを呼び出してから、最終的に Stop メソッドを呼び出し、Elapsed プロパティを使用して経過時間を確認します。
Stopwatch インスタンスには、実行中と停止中の状態があります。Stopwatch の現在の状態を判断するには、IsRunning を使用します。経過時間の計測を開始するには、Start を使用します。経過時間の計測を停止するには、Stop を使用します。経過時間の値を問い合わせるには、Elapsed、ElapsedMilliseconds、または ElapsedTicks の各プロパティを使用します。インスタンスの実行中または停止中に経過時間のプロパティを問い合わせることができます。経過時間のプロパティは、Stopwatch の実行中は徐々に増加し、インスタンスの停止中は変化しません。
既定では、Stopwatch インスタンスの経過時間の値は、計測されたすべての時間間隔の合計と等しくなります。Start を呼び出すたびに、累積経過時間のカウントが開始されます。Stop を呼び出すたびに、現在の間隔計測を終了して、累積経過時間の値を固定します。既存の Stopwatch インスタンスの累積経過時間を消去するには、Reset メソッドを使用します。
Stopwatch は、基になるタイマ機構のタイマ刻みをカウントして、経過時間を計測します。インストールされているハードウェアおよびオペレーティング システムが高解像力のパフォーマンス カウンタをサポートしている場合、Stopwatch クラスはそのカウンタを使用して経過時間を計測します。それ以外の場合、Stopwatch クラスはシステム タイマを使用して経過時間を計測します。Stopwatch タイミング実装の精度および解像力を判断するには、Frequency フィールドおよび IsHighResolution フィールドを使用します。
Stopwatch クラスは、マネージ コード内のタイミング関連パフォーマンス カウンタの操作を支援します。特に、Frequency フィールドおよび GetTimestamp メソッドは、アンマネージ Win32 API QueryPerformanceFrequency および QueryPerformanceCounter の代わりに使用できます。

構文解説返された Stopwatch インスタンスは停止し、インスタンスの経過時間のプロパティはゼロになります。
新しい Stopwatch インスタンスを使用して経過時間の計測を開始するには、Start メソッドを使用します。新しい Stopwatch インスタンスを初期化してすぐに開始するには、StartNew メソッドを使用します。
使用例単純なクラス コンストラクタ内で Stopwatch インスタンスを初期化する例を次に示します。このコード例は、Stopwatch クラスのトピックで取り上げているコード例の一部分です。
Dim stopWatch As StopWatch Dim captureLap As Boolean Public Sub New() MyBase.New() stopwatch = New StopWatch() captureLap = False InitializeComponent() End Sub
private Stopwatch stopWatch; private Boolean captureLap; public FormMain() { stopWatch = new Stopwatch(); captureLap = false; InitializeComponent(); }

Stopwatch（ストップウォッチ）はその名の通り、実際のストップウォッチのように手での操作で計時を可能にするデスクトップ用のアプレットである。また、カウントダウン用のタイマーとしても使用できる。
概要
ストップウォッチはミリ秒単位の精度を持ち、測定可能な時間にシステム上の制限はない。ストップウォッチは、UNIX や Windows、MacOS上で動作する。通常、ストップウォッチはスタンドアロンのプログラムとして動作します。また、Tcl プラグインがあれば、ブラウザ上でも動作させることができる。
Tk 8.3 以降のバージョンをサポートすればどのようなシステムでも動作する[1]。
