TimeSpan.FromMilliseconds メソッド

.NET Framework クラス ライブラリ リファレンス

TimeSpan.FromMilliseconds メソッド

指定したミリ秒数を表す TimeSpan を返します。

名前空間: System
アセンブリ: mscorlib (mscorlib.dll 内)
構文

Visual Basic (宣言)

Public Shared Function FromMilliseconds
 ( _
    value As Double _
) As TimeSpan

Visual Basic (使用法)

Dim value As Double
Dim returnValue As TimeSpan

returnValue = TimeSpan.FromMilliseconds(value)

C#

public static TimeSpan FromMilliseconds (
    double value
)

C++

public:
static TimeSpan FromMilliseconds (
    double value
)

J#

public static TimeSpan FromMilliseconds (
    double value
)

JScript

public static function FromMilliseconds
 (
    value : double
) : TimeSpan

パラメータ

value

ミリ秒数。

戻り値
value を表す TimeSpan。

例外

例外の種類	条件
OverflowException	value が MinValue より小さい値か、MaxValue より大きい値です。
ArgumentException	value と Double.NaN が等価です。

解説

value パラメータはタイマ刻みに変換され、このタイマ刻みの数を使用して新しい TimeSpan が初期化されます。したがって、value は、ミリ秒単位の精度であると見なされます。

value が Double.PositiveInfinity の場合は、MaxValue が返されます。value が Double.NegativeInfinity の場合は、MinValue が返されます。

使用例

FromMilliseconds メソッドを使用して、複数の TimeSpan オブジェクトを作成するコード例を次に示します。
