Point.Equality(Point, Point) 运算符

定义

命名空间:

System.Drawing

程序集:

System.Drawing.Primitives.dll

Source:

Point.cs

比较两个 Point 对象。 此结果指定两个 X 对象的 Y 和 Point 属性的值是否相等。

public:
 static bool operator ==(System::Drawing::Point left, System::Drawing::Point right);

public static bool operator == (System.Drawing.Point left, System.Drawing.Point right);

static member ( = ) : System.Drawing.Point * System.Drawing.Point -> bool

Public Shared Operator == (left As Point, right As Point) As Boolean

参数

left

Point

要比较的 Point。

right

Point

要比较的 Point。

返回

Boolean

如果 left 和 right 的 X 和 Y 值均相等，则为 true；否则为 false。

示例

下面的代码示例演示如何使用 Equality 运算符以及如何从一Size个或两个Point整数构造 。 它还演示如何使用 X 和 Y 属性。 此示例旨在与 Windows 窗体 一起使用。 将代码粘贴到包含名为 的 Button1按钮的窗体中 Button1_Click ，并将 方法与按钮的 Click 事件相关联。

private:
   void Button1_Click( System::Object^ /*sender*/, System::EventArgs^ /*e*/ )
   {
      // Construct a new Point with integers.
      Point Point1 = Point(100,100);

      // Create a Graphics object.
      Graphics^ formGraphics = this->CreateGraphics();

      // Construct another Point, this time using a Size.
      Point Point2 = Point(System::Drawing::Size( 100, 100 ));

      // Call the equality operator to see if the points are equal,  
      // and if so print out their x and y values.
      if ( Point1 == Point2 )
      {
         array<Object^>^temp0 = {Point1.X,Point2.X,Point1.Y,Point2.Y};
         formGraphics->DrawString( String::Format( "Point1.X: "
         "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}", temp0 ), this->Font, Brushes::Black, PointF(10,70) );
      }
   }

private void Button1_Click(System.Object sender, System.EventArgs e)
{

    // Construct a new Point with integers.
    Point Point1 = new Point(100, 100);

    // Create a Graphics object.
    Graphics formGraphics = this.CreateGraphics();

    // Construct another Point, this time using a Size.
    Point Point2 = new Point(new Size(100, 100));

    // Call the equality operator to see if the points are equal,  
    // and if so print out their x and y values.
    if (Point1 == Point2)
    {
        formGraphics.DrawString(String.Format("Point1.X: " +
            "{0},Point2.X: {1}, Point1.Y: {2}, Point2.Y {3}",
            new object[]{Point1.X, Point2.X, Point1.Y, Point2.Y}),
            this.Font, Brushes.Black, new PointF(10, 70));
    }
}
