EditPoint2.LessThan(TextPoint) Método

Definição

Retorna se o valor do objeto chamado EditPoint AbsoluteCharOffset é menor do que o do TextPoint objeto fornecido.

public:
 bool LessThan(EnvDTE::TextPoint ^ Point);
public:
 bool LessThan(EnvDTE::TextPoint ^ Point);
bool LessThan(EnvDTE::TextPoint const & Point);
[System.Runtime.InteropServices.DispId(32)]
public bool LessThan (EnvDTE.TextPoint Point);
[<System.Runtime.InteropServices.DispId(32)>]
abstract member LessThan : EnvDTE.TextPoint -> bool
Public Function LessThan (Point As TextPoint) As Boolean

Parâmetros

Point
TextPoint

Obrigatórios. Um TextPoint para comparar com o objeto de ponto de chamada.

Retornos

Boolean

true Se Point tem um valor de propriedade maior do AbsoluteCharOffset que a propriedade do objeto de ponto de chamada AbsoluteCharOffset ; caso contrário, false .

Comentários

LessThan gera um ArgumentException If Point que não está no mesmo documento que o objeto de ponto de chamada. Com o VirtualPoint objeto, o LessThan compara as posições virtuais se o argumento for a VirtualPoint . Caso contrário, ele compara as posições físicas.
