'Declaration
 
Public Shared Function LessThanOrEqual( _
   ByVal left As TdPeriodDate, _
   ByVal right As TdPeriodDate _
) As Boolean

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

public static bool LessThanOrEqual( 
   TdPeriodDate left,
   TdPeriodDate right
)

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

Parameters

left

An instance of TdPeriodDate.

right

An instance of TdPeriodDate.

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.
