示例1: ConvertRectangleToRectangleF
Private Sub ConvertRectangleToRectangleF( _
ByVal e As PaintEventArgs)
' Create a rectangle.
Dim rectangle1 As New Rectangle(30, 40, 50, 100)
' Convert it to a RectangleF.
Dim convertedRectangle As RectangleF = _
RectangleF.op_Implicit(rectangle1)
' Create a new RectangleF.
Dim rectangle2 As New RectangleF(New PointF(30.0F, 40.0F), _
New SizeF(50.0F, 100.0F))
' Create a custom, partially transparent brush.
Dim redBrush As New SolidBrush(Color.FromArgb(40, Color.Red))
' Compare the converted rectangle with the new one. If they
' are equal, draw and fill the rectangles on the form.
If (RectangleF.op_Equality(convertedRectangle, rectangle2)) Then
e.Graphics.FillRectangle(redBrush, rectangle2)
End If
' Dispose of the custom brush.
redBrush.Dispose()
End Sub示例2: RoundingAndTruncatingRectangles
Private Sub RoundingAndTruncatingRectangles( _
ByVal e As PaintEventArgs)
' Construct a new RectangleF.
Dim myRectangleF As New RectangleF(30.6F, 30.7F, 40.8F, 100.9F)
' Call the Round method.
