判斷指定點的座標是否不相等。

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

參數

left
PointF

A PointF 來比較。

right
PointF

A PointF 來比較。

傳回

Boolean

true表示 X 和 Y 的值leftright不相等;否則 。 false

範例

以下程式碼範例示範如何使用運算 Inequality 子。 要執行此範例，請將以下程式碼貼上到 Windows 表單中。 處理該型態的Paint事件，並呼叫 AddExample，通過 e 。PaintEventArgs

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
