PointF.Equality(PointF, PointF) 运算符

定义

比较两个 PointF 结构。Compares two PointF structures. 此结果指定两个 X 结构的 YPointF 属性的值是否相等。The result specifies whether the values of the X and Y properties of the two PointF structures are equal.

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

参数

left
PointF

要比较的 PointFA PointF to compare.

right
PointF

要比较的 PointFA PointF to compare.

返回

如果左边和右边的 true 结构的 XY 值相等,为 PointF;否则为 falsetrue if the X and Y values of the left and right PointF structures are equal; otherwise, false.

示例

下面的代码示例演示如何使用 Equality 运算符。The following code example demonstrates how to use the Equality operator. 若要运行此示例,请将以下代码粘贴到 Windows 窗体中。To run this example, paste the following code into a Windows Form. 处理窗体的 Paint 事件并调用 opAdditionExample,将 e 作为 PaintEventArgs传递。Handle the form's Paint event and call opAdditionExample, passing e as PaintEventArgs.

private void OpAdditionExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(120.5F, 30.5F);
    RectangleF rect1 = new RectangleF(point1, size1);
    if (new PointF(rect1.Right, rect1.Bottom) == point1 + size1)
        e.Graphics.DrawString("They are equal", this.Font, Brushes.Black, rect1);
    else
        e.Graphics.DrawString("They are not equal", this.Font, Brushes.Red, rect1);
}
Private Sub OpAdditionExample(ByVal e As PaintEventArgs) 
    Dim size1 As New SizeF(120.5F, 30.5F)
    Dim point1 As New PointF(20.5F, 20F)
    Dim rect1 As New RectangleF(point1, size1)
    If New PointF(rect1.Right, rect1.Bottom) = point1 + size1 Then
        e.Graphics.DrawString("They are equal", Me.Font, Brushes.Black, rect1)
    Else
        e.Graphics.DrawString("They are not equal", Me.Font, Brushes.Red, rect1)
    End If
 
End Sub
