TimeSpan.Add メソッド
指定した TimeSpan と、このインスタンスを加算します。
Public Function Add( _
ByVal ts As TimeSpan _) As TimeSpan
[C#]
public TimeSpan Add(TimeSpants);
[C++]
public: TimeSpan Add(TimeSpants);
[JScript]
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
| 例外の種類 | 条件 |
|---|---|
| OverflowException | 生成される TimeSpan が MinValue より小さい値か、 MaxValue より大きい値です。 |
解説
戻り値は、 MinValue と MaxValue の間の数値であることが必要です。それ以外の場合は例外がスローされます。
戻り値は新しい TimeSpan です。元の TimeSpan は変更しません。
使用例
[Visual Basic, C#, C++] TimeSpan オブジェクトの複数のペアを作成し、各ペアの和を Add メソッドで計算するコード例を次に示します。
