示例1: EnumerateExample

Public Sub EnumerateExample(ByVal e As PaintEventArgs)
    Dim myPath As New GraphicsPath
    Dim myPoints As Point() = {New Point(20, 20), _
        New Point(120, 120), New Point(20, 120), New Point(20, 20)}
    Dim myRect As New Rectangle(120, 120, 100, 100)
    myPath.AddLines(myPoints)
    myPath.AddRectangle(myRect)
    myPath.AddEllipse(220, 220, 100, 100)

    ' Get the total number of points for the path, and arrays of the
    ' points and types.
    Dim myPathPointCount As Integer = myPath.PointCount
    Dim myPathPoints As PointF() = myPath.PathPoints
    Dim myPathTypes As Byte() = myPath.PathTypes

    ' Set up variables for listing the array of points on the left side
    ' of the screen.
    Dim i As Integer
    Dim j As Single = 20
    Dim myFont As New Font("Arial", 8)
    Dim myBrush As New SolidBrush(Color.Black)

    ' List the set of points and types and types to the left side of
    ' the screen.
    e.Graphics.DrawString("Original Data", myFont, myBrush, 20, j)
    j += 20
    For i = 0 To myPathPointCount - 1
        e.Graphics.DrawString(myPathPoints(i).X.ToString() & ", " & _
        myPathPoints(i).Y.ToString() & ", " & _
        myPathTypes(i).ToString(), myFont, myBrush, 20, j)

    ' Draw the set of copied points and types to the screen.
    j = 20
    e.Graphics.DrawString("Copied Data", myFont, myBrush, 200, j)
    j += 20
