Public Shared Function LessThanOrEqual( _
   ByVal left As TdPeriodTimeWithTimeZone, _
   ByVal right As TdPeriodTimeWithTimeZone _
) As Boolean

'Usage
 
Dim left As TdPeriodTimeWithTimeZone
Dim right As TdPeriodTimeWithTimeZone
Dim value As Boolean
 
value = TdPeriodTimeWithTimeZone.LessThanOrEqual(left, right)

public static bool LessThanOrEqual( 
   TdPeriodTimeWithTimeZone left,
   TdPeriodTimeWithTimeZone right
)

public:
static bool LessThanOrEqual( 
   TdPeriodTimeWithTimeZone left,
   TdPeriodTimeWithTimeZone right
) 

Parameters

left

An instance of TdPeriodTimeWithTimeZone.

right

An instance of TdPeriodTimeWithTimeZone.

Return Value

In order to perform this comparison the beginning and ending bounds of the left and right operands are compared against each other. The left is equal to or less than the right if the following is true:

    ((left.Begin < right.Begin) OR (left.Begin == right.Begin AND left.End <= right.End))

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

Comparison operators always returns false if one of the operands is Null. Therefore, you must not assume that the reverse condition is true. For example you cannot assume that the left operand is greater than the right operand if the LessThanOrEqual operator returns false.
