RectangleF.Equality(RectangleF, RectangleF) Operador

Definição

Testa se duas estruturas RectangleF têm local e tamanho iguais.Tests whether two RectangleF structures have equal location and size.

public:
 static bool operator ==(System::Drawing::RectangleF left, System::Drawing::RectangleF right);
public static bool operator == (System.Drawing.RectangleF left, System.Drawing.RectangleF right);
static member ( = ) : System.Drawing.RectangleF * System.Drawing.RectangleF -> bool
Public Shared Operator == (left As RectangleF, right As RectangleF) As Boolean

Parâmetros

left
RectangleF

A estrutura RectangleF que está à esquerda do operador de igualdade.The RectangleF structure that is to the left of the equality operator.

right
RectangleF

A estrutura RectangleF que está à direita do operador de igualdade.The RectangleF structure that is to the right of the equality operator.

Retornos

true se as duas estruturas RectangleF têm as propriedades X, Y, Width e Height iguais; caso contrário, false.true if the two specified RectangleF structures have equal X, Y, Width, and Height properties; otherwise, false.

Exemplos

O exemplo de código a seguir demonstra como usar Implicitos RectangleF Membros Equality e.The following code example demonstrates how to use the Implicit, RectangleF and Equality members. Este exemplo foi projetado para uso com um Windows Form.This example is designed for use with a Windows Form.
