using System;

        // does not contain milliseconds.

注釈

value パラメーターはミリ秒に変換され、ティックに変換され、そのティック数を使用して新しいTimeSpanを初期化します。 したがって、 value は最も近いミリ秒に対してのみ正確と見なされます。 Doubleデータ型の精度が失われるため、この変換により、OverflowExceptionまたはMinValueの範囲内にある値のMaxValueが生成される可能性があることに注意してください。 たとえば、次の試行でOverflowException オブジェクトをインスタンス化しようとすると、TimeSpanが発生します。

// The following throws an OverflowException at runtime
TimeSpan maxSpan = TimeSpan.FromHours(TimeSpan.MaxValue.TotalHours);

// The following throws an OverflowException at runtime
let maxSpan = TimeSpan.FromHours TimeSpan.MaxValue.TotalHours

' The following throws an OverflowException at runtime
Dim maxSpan As TimeSpan = TimeSpan.FromHours(TimeSpan.MaxValue.TotalHours)
