Public Shared Function LessThanOrEqual( _

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

public static bool LessThanOrEqual( 
   TdPeriodTimestampWithTimeZone left,
   TdPeriodTimestampWithTimeZone right
)

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

Parameters

left

An instance of TdPeriodTimestampWithTimeZone.

right

An instance of TdPeriodTimestampWithTimeZone.

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.
