Contains(Point)
public:
bool Contains(System::Drawing::Point pt);
public bool Contains (System.Drawing.Point pt);
member this.Contains : System.Drawing.Point -> bool
Public Function Contains (pt As Point) As Boolean
Parâmetros
Retornos
Esse método retorna true se o ponto representado por pt está contido nessa estrutura Rectangle; caso contrário, false.This method returns true if the point represented by pt is contained within this Rectangle structure; otherwise false.
Comentários
O retângulo de contenção deve ser normalizado para que esse método retorne resultados precisos.The containing rectangle must be normalized for this method to return accurate results.

Contains(Rectangle)
public:
bool Contains(System::Drawing::Rectangle rect);
public bool Contains (System.Drawing.Rectangle rect);
member this.Contains : System.Drawing.Rectangle -> bool
Public Function Contains (rect As Rectangle) As Boolean
Parâmetros
Retornos
Este método retornará true se a região retangular representada por rect estiver inteiramente contida dentro desta estrutura Rectangle; caso contrário, false.This method returns true if the rectangular region represented by rect is entirely contained within this Rectangle structure; otherwise false.
Exemplos
O exemplo de código a seguir demonstra o Contains método e a SystemPens classe.The following code example demonstrates the Contains method and the SystemPens class. Este exemplo foi projetado para uso com um Windows Form.This example is designed for use with a Windows Form. Cole esse código em um formulário que contém um botão chamado Button1 , chame DrawFirstRectangle do construtor ou do método do formulário Load e associe o Button1_Click método ao evento do botão Click .Paste this code into a form that contains a button named Button1, call DrawFirstRectangle from the form's constructor or Load method, and associate the Button1_Click method with the button's Click event.

O retângulo de contenção deve ser normalizado para que esse método retorne resultados precisos.The containing rectangle must be normalized for this method to return accurate results.
Aplica-se a
Contains(Int32, Int32)
public:
bool Contains(int x, int y);
public bool Contains (int x, int y);
member this.Contains : int * int -> bool
Public Function Contains (x As Integer, y As Integer) As Boolean
Parâmetros
- x
- Int32
A coordenada X do ponto a ser testado.The x-coordinate of the point to test.
- y
- Int32
A coordenada Y do ponto a ser testado.The y-coordinate of the point to test.
Retornos
Este método retornará true se o ponto definido por x e y estiver contido dentro desta estrutura Rectangle; caso contrário, false.This method returns true if the point defined by x and y is contained within this Rectangle structure; otherwise false.
