PointF.Inequality(PointF, PointF) 运算符

定义

命名空间:

System.Drawing

程序集:

System.Drawing.Primitives.dll

Source:

PointF.cs

确定指定点的坐标是否不等。

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 op_Inequality : 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 PointF。

right

PointF

要比较的 PointF。

返回

Boolean

要指示 left 和 right 的 X 和 Y 值不等，为 true；否则为 false。

示例

下面的代码示例演示如何使用 Inequality 运算符。 若要运行此示例，请将以下代码粘贴到 Windows 窗体中。 处理窗体的 Paint 事件并调用 AddExample，作为 ePaintEventArgs传递。

private void AddExample(PaintEventArgs e)
{
    PointF point1 = new PointF(120.5F, 120F);
    SizeF size1 = new SizeF(20.5F, 20.5F);
    RectangleF rect1 = new RectangleF(point1, size1);
    PointF point2 = new PointF(rect1.Right, rect1.Bottom);
    if (point2 != PointF.Add(point1, size1))
        e.Graphics.DrawString("They are not equal", this.Font, Brushes.Red, rect1);
    else
        e.Graphics.DrawString("They are equal", this.Font, Brushes.Black, rect1);
}

Private Sub AddExample(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)
    Dim point2 As New PointF(rect1.Right, rect1.Bottom)
    If point2 <> PointF.Add(point1, size1) Then
        e.Graphics.DrawString("They are not equal", Me.Font, Brushes.Red, rect1)
    Else
        e.Graphics.DrawString("They are equal", Me.Font, Brushes.Black, rect1)
    End If

End Sub
