equivalentCodeEntityM:System.DateTimeOffset.Equals(System.DateTimeOffset,System.DateTimeOffset)

Determines whether two specified DateTimeOffset objects represent the same point in time.

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

public static bool operator ==(
	DateTimeOffset left,
	DateTimeOffset right
)

Parameters

left
Type: System.DateTimeOffset

The first object to compare.

right
Type: System.DateTimeOffset

The second object to compare.

Return Value

Type: System.Boolean

true if both DateTimeOffset objects have the same UtcDateTime value; otherwise, false.

The Equality method defines the operation of the equality operator for DateTimeOffset objects. It enables code such as the following:

DateTimeOffset date1 = new DateTimeOffset(2007, 6, 3, 14, 45, 0, 
             new TimeSpan(-7, 0, 0));
DateTimeOffset date2 = new DateTimeOffset(2007, 6, 3, 15, 45, 0,
             new TimeSpan(-6, 0, 0));
DateTimeOffset date3 = new DateTimeOffset(date1.DateTime, 
             new TimeSpan(-6, 0, 0));
Console.WriteLine(date1 == date2);        // Displays True
Console.WriteLine(date1 == date3);        // Displays False 

Before evaluating the left and right operands for equality, the operator converts both values to Coordinated Universal Time (UTC). The operation is equivalent to the following:

return first.UtcDateTime == second.UtcDateTime;

In other words, the Equality method determines whether the two DateTimeOffset objects represent a single point in time. It directly compares neither dates and times nor offsets. To determine whether two DateTimeOffset objects represent the same time and have the same offset value, use the EqualsExact method.
