Namespace:  System
Assembly:  mscorlib (in mscorlib.dll)

public static DateTimeOffset operator +(
	DateTimeOffset dateTimeTz,
	TimeSpan timeSpan
)

Parameters

dateTimeTz
Type: System.DateTimeOffset

A DateTimeOffset object.

timeSpan
Type: System.TimeSpan

A TimeSpan object that specifies the time interval to add to the DateTimeOffset object.

Return Value

Type: System.DateTimeOffset
A DateTimeOffset object whose value is the sum of the values of dateTimeTz and timeSpan.

ExceptionCondition
ArgumentOutOfRangeException

The resulting DateTimeOffset value is less than MinValue.

-or-

The resulting DateTimeOffset value is greater than MaxValue.

The Addition method defines the addition operation for DateTimeOffset values. It enables code such as the following:

DateTimeOffset date1 = new DateTimeOffset(2008, 1, 1, 13, 32, 45, 
                       new TimeSpan(-5, 0, 0)); 
TimeSpan interval1 = new TimeSpan(202, 3, 30, 0);
TimeSpan interval2 = new TimeSpan(5, 0, 0, 0);      
DateTimeOffset date2; 

Console.WriteLine(date1);         // Displays 1/1/2008 1:32:45 PM -05:00
date2 = date1 + interval1;
Console.WriteLine(date2);         // Displays 7/21/2008 5:02:45 PM -05:00
date2 += interval2;
Console.WriteLine(date2);         // Displays 7/26/2008 5:02:45 PM -05:00     

Languages that do not support custom operators and operator overloading can call the Add method instead.
