TimeSpan.Add メソッドとは? わかりやすく解説

TimeSpan.Add メソッド

指定した TimeSpan と、このインスタンス加算します。

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

Public Function Add ( _
    ts As TimeSpan _
) As TimeSpan
Dim instance As TimeSpan
Dim ts As TimeSpan
Dim returnValue As TimeSpan

returnValue = instance.Add(ts)
public TimeSpan Add (
    TimeSpan ts
)
public:
TimeSpan Add (
    TimeSpan ts
)
public TimeSpan Add (
    TimeSpan ts
)
public function Add (
    ts : TimeSpan
) : TimeSpan

パラメータ

ts

TimeSpan。

戻り値
このインスタンスの値と ts の値の合計を表す TimeSpan

例外例外
例外種類条件

OverflowException

結果として得られる TimeSpan が MinValue より小さい値か、MaxValue より大きい値です。

解説解説

戻り値は、MinValueMaxValue の間の数値であることが必要です。それ以外場合例外スローさます。

戻り値新しTimeSpan です。元の TimeSpan変更しません。
