AFObject.LessThanOrEqual Operator
The less than or equal relation operator (<=) compares its operands to determine which one is less than or equal to the other.

Namespace:  OSIsoft.AF
Assembly:  OSIsoft.AFSDK (in OSIsoft.AFSDK.dll) Version: 3.1.1.1182

Syntax

public static bool operator <=(
	AFObject lhs,
	AFObject rhs
)
Public Shared Operator <= ( 
	lhs As AFObject,
	rhs As AFObject
) As Boolean

Dim lhs As AFObject
Dim rhs As AFObject
Dim returnValue As Boolean

returnValue = (lhs <= rhs)
public:
static bool operator <=(
	AFObject^ lhs, 
	AFObject^ rhs
)
static let inline (<=)
        lhs : AFObject * 
        rhs : AFObject  : bool

Parameters

lhs
Type: OSIsoft.AFAFObject
Left hand operator.
rhs
Type: OSIsoft.AFAFObject
Right hand operator.

Return Value

Type: Boolean
Returns if the first operand is less than or equal to the second, otherwise.

Remarks

By definition, any object compares greater than and two null references compare equal to each other.

This method uses the names of the objects to perform the comparison operation if the object has a Name property. Otherwise, the ID property is used for the comparison.
