TimeSpan.op_Addition メソッド

指定した 2 つの TimeSpan インスタンスを加算します。

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

Visual Basic (宣言)

Public Shared Operator + ( _
    t1 As TimeSpan, _
    t2 As TimeSpan _
) As TimeSpan

Visual Basic (使用法)

Dim t1 As TimeSpan
Dim t2 As TimeSpan
Dim returnValue As TimeSpan

returnValue = (t1 + t2)

public static TimeSpan operator + (
    TimeSpan t1,
    TimeSpan t2
)

C++

public:
static TimeSpan operator + (
    TimeSpan t1, 
    TimeSpan t2
)

J# では、オーバーロードされた演算子は使用できません。

JScript

JScriptでは、 オーバーロードされた演算子は使用できますが、新規に宣言することはできません。

パラメータ

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	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。

使用例

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。
