TimeSpan 加算演算子

2008-03-28

指定した 2 つの TimeSpan インスタンスを加算します。

returnValue = TimeSpan.op_Addition(t1, t2)
[C#]
public static TimeSpan operator +(TimeSpant1,TimeSpant2);
[C++]
public: static TimeSpan op_Addition(TimeSpant1,TimeSpant2);
[JScript]
returnValue = t1 + t2;

[Visual Basic] Visual Basic では、この型で定義されている演算子を使用することができます。ただし、独自に定義することはできません。Add メソッドを TimeSpan 加算演算子の代わりに使用することができます。

[JScript] JScript では、この型で定義されている演算子を使用することができます。ただし、独自に定義することはできません。

引数 [Visual Basic, JScript]

t1
TimeSpan 。
t2
TimeSpan 。

パラメータ [C#, C++]

t1
TimeSpan 。
t2
TimeSpan 。

戻り値

t1 の値と t2 の値の合計を値とする 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。

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 Addition 演算子で計算するコード例を次に示します。
