Metodo EditPoint.GreaterThan (TextPoint)

Articolo
10/30/2012

Restituisce un valore che indica se il valore della proprietà AbsoluteCharOffset dell'oggetto TextPoint è maggiore di quello dell'oggetto EditPoint specificato.

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

Sintassi

'Dichiarazione
Function GreaterThan ( _
    Point As TextPoint _
) As Boolean

bool GreaterThan(
    TextPoint Point
)

bool GreaterThan(
    [InAttribute] TextPoint^ Point
)

abstract GreaterThan : 
        Point:TextPoint -> bool

function GreaterThan(
    Point : TextPoint
) : boolean

Parametri

Point
Tipo: EnvDTE.TextPoint
Necessario.Oggetto TextPoint da confrontare all'oggetto punto chiamante.

Valore restituito

Tipo: System.Boolean
true se Point presenta un valore della proprietà AbsoluteCharOffset inferiore rispetto alla proprietà AbsoluteCharOffset dell'oggetto EditPoint chiamante; in caso contrario false.

Note

GreaterThan genera un'eccezione ArgumentException se Point non si trova nello stesso documento dell'oggetto chiamante.Con l'oggetto VirtualPoint, il metodo GreaterThan confronta le posizioni virtuali se l'argomento è un oggetto VirtualPoint.In caso contrario confronta le posizioni "fisiche".
