Equality Operator (TdTimestampWithTimeZone)

Compares two TdTimestampWithTimeZones to determine whether the operand is equal to the operand.

Syntax

Visual Basic
C#
C++/CLI

'Declaration
 
Public Operator =( _
   ByVal left As TdTimestampWithTimeZone, _
   ByVal right As TdTimestampWithTimeZone _
) As Boolean

'Usage

public bool operator ==( 
   TdTimestampWithTimeZone left,
   TdTimestampWithTimeZone right
)

public:
bool operator ==( 
   TdTimestampWithTimeZone left,
   TdTimestampWithTimeZone right
)

Parameters

left: An instance of TdTimestampWithTimeZone.
right: An instance of TdTimestampWithTimeZone.

Return Value

A boolean is returned that indicates the result of the comparison.

Remarks

The value returned is true if the left is equal to the right, false otherwise.

Return Value Description

Return Value	Description
`true`	left and right are TdTimestampWithTimeZone.Null -or- left is equal to right.
`false`	left or right is Null -or- left is not equal to right.

true

left and right are TdTimestampWithTimeZone.Null

-or-

left is equal to right.

false

left or right is Null

-or-

left is not equal to right.

Unlike comparison operators, Equality operators do not always return false when left and right operands are Null. Therefore the reverse condition can be considered true. TdTimestampWithTimeZone implementation is very similar to the Nullable class in this regard.

For more information on how the comparison is performed refer to TdTimestampWithTimeZone.CompareTo.

Example

Following example shows that the Equality operator can safely be used in an if statement.

TdTimestampWithTimeZone x = TdTimestampWithTimeZone.Null;
TdTimestampWithTimeZone y = TdTimestampWithTimeZone.MinValue;
            
if (x == y)
{
    // x is equal to y.
    Console.WriteLine(@"X is equal to Y").
}
else
{
    // x is not equal y
    Console.WriteLine(@"X is not equal to Y").
}
            
y = TdTimestampWithTimeZone.Null;
            
if (x == y)
{
    // x is equal to y.
    Console.WriteLine(@"X is equal to Y").
}
else
{
    // x is not equal y
    Console.WriteLine(@"X is not equal to Y").
}
