Metodo EditPoint2.LessThan (TextPoint)

Restituisce se il valore del chiamato EditPoint oggetto AbsoluteCharOffset è inferiore a quello del controllo specificato TextPoint oggetto.

Spazio dei nomi:  EnvDTE80
Assembly:  EnvDTE80 (in EnvDTE80.dll)

Sintassi

'Dichiarazione
Function LessThan ( _
    Point As TextPoint _
) As Boolean
bool LessThan(
    TextPoint Point
)
bool LessThan(
    [InAttribute] TextPoint^ Point
)
abstract LessThan : 
        Point:TextPoint -> bool 
function LessThan(
    Point : TextPoint
) : boolean

Parametri

Valore restituito

Tipo: System.Boolean
true se Point dispone di un maggior AbsoluteCharOffset valore della proprietà che l'oggetto del punto chiamante AbsoluteCharOffset proprietà; in caso contrario, false.

Note

LessThan genera un'eccezione ArgumentException se Point non si tratta dello stesso documento dell'oggetto del punto chiamante.con VirtualPoint oggetto, LessThan confronta i percorsi virtuali se l'argomento è un oggetto VirtualPoint.In caso contrario confrontano le posizioni fisiche.
