Assembly:

System.Runtime.dll

Source:

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

Parameters

d

DateTime

The date and time value to add.

t

TimeSpan

The time interval to add.

Returns

DateTime

An object that is the sum of the values of d and t.

Exceptions

ArgumentOutOfRangeException

The resulting DateTime is less than DateTime.MinValue or greater than DateTime.MaxValue.

Examples

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;

let dTime = DateTime(1980, 8, 5)

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

// Result gets 8/22/1980 4:02:01 AM.
let 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

Remarks

The equivalent method for this operator is DateTime.Add(TimeSpan)
