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

Visual Basic (宣言)

Public Overridable Function
 AddSeconds ( _
    time As DateTime, _
    seconds As Integer _
) As DateTime

Visual Basic (使用法)

Dim instance As Calendar
Dim time As DateTime
Dim seconds As Integer
Dim returnValue As DateTime

returnValue = instance.AddSeconds(time, seconds)

public virtual DateTime AddSeconds (
    DateTime time,
    int seconds
)

C++

public:
virtual DateTime AddSeconds (
    DateTime time, 
    int seconds
)

public DateTime AddSeconds (
    DateTime time, 
    int seconds
)

JScript

public function AddSeconds (
    time : DateTime, 
    seconds : int
) : DateTime

パラメータ

time: 秒数を加算する対象の DateTime。

seconds: 加算する秒数。

戻り値
指定した DateTime に指定した秒数を加算した結果の DateTime。

例外

例外の種類	条件
ArgumentException	結果として得られる DateTime がこの暦でサポートされている範囲外の値です。
ArgumentOutOfRangeException	seconds 自体が DateTime の戻り値でサポートされている範囲外の値です。

解説

seconds 値が指定された DateTime に加算されます。seconds が負の場合、結果の DateTime は、指定した DateTime よりも前の値になります。

使用例

Calendar クラスのメンバの使用例を次に示します。
