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

'Usage
 

public bool operator <=( 
   TdPeriodDate left,
   TdPeriodDate right
)

public:
bool operator <=( 
   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 || (left.Begin == right.Begin && left.End <= right.End)

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 "<=" operator returns false.
