定義

指定した日付と時刻に指定した時間間隔を加算して、新しい日付と時刻を作成します。Adds a specified time interval to a specified date and time, yielding a new date and time.

public:
 static DateTime operator +(DateTime d, TimeSpan t);
public static DateTime operator + (DateTime d, TimeSpan t);
static member ( + ) : DateTime * TimeSpan -> DateTime
Public Shared Operator + (d As DateTime, t As TimeSpan) As DateTime

パラメーター

d
DateTime

追加する日付と時刻の値。The date and time value to add.

t
TimeSpan

加算する時間間隔。The time interval to add.

戻り値

dt を加算した値であるオブジェクト。An object that is the sum of the values of d and t.

例外

結果として返された DateTimeMinValue より小さいか、MaxValue より大きいです。The resulting DateTime is less than MinValue or greater than MaxValue.

加算演算子の例を次に示します。The following example demonstrates the addition operator.

System::DateTime dTime( 1980, 8, 5 );

// tSpan is 17 days, 4 hours, 2 minutes and 1 second.
System::TimeSpan tSpan( 17, 4, 2, 1 );

// Result gets 8/22/1980 4:02:01 AM.
System::DateTime result = dTime + tSpan;
System.DateTime dTime = new System.DateTime(1980, 8, 5);

// tSpan is 17 days, 4 hours, 2 minutes and 1 second.
System.TimeSpan tSpan 
    = new System.TimeSpan(17, 4, 2, 1); 

// Result gets 8/22/1980 4:02:01 AM.
System.DateTime result = dTime + tSpan;
Dim dTime As Date = #8/5/1980#

' tSpan is 17 days, 4 hours, 2 minutes and 1 second.
Dim tSpan As New TimeSpan(17, 4, 2, 1)

Dim result1, result2 As Date

' Result gets 8/22/1980 4:02:01 AM.
result1 = Date.op_Addition(dTime, tSpan)

result2 = dTime + tSpan 

注釈

この演算子の同等のメソッドは DateTime.Add(TimeSpan)The equivalent method for this operator is DateTime.Add(TimeSpan)
