CustomLineCap.Clone 方法
重要

建立這個 CustomLineCap的確切複本。
public:
virtual System::Object ^ Clone();C#
public object Clone ();abstract member Clone : unit -> obj
override this.Clone : unit -> objPublic Function Clone () As Object這個方法 CustomLineCap 建立，並轉換成 物件。
下列範例的設計目的是要與 Windows Forms 搭配使用，而且需要 PaintEventArgsePaint 事件物件。 程式代碼會執行下列動作：
使用 GraphicsPath 物件建立自定義行上限。
使用剛建立的 GraphicsPath 物件，建立 CustomLineCap 物件，
firstCap。使用 Clone 方法建立
firstCap的複本。設定 Pen 物件的 CustomStartCap 和 CustomEndCap 屬性，並使用該畫筆繪製線條和自定義大寫字母到螢幕。
Public Sub CloneExample(e As PaintEventArgs)
Dim points As Point() = New Point(- 5, - 5) New Point(0, 0) _
New Point(5, - 5)
Dim capPath As New GraphicsPath()
' Create a Path and add two lines to it,
' forming a custom line cap.
capPath.AddLines(points)
' Create a CustomLineCap object.
Dim firstCap As New CustomLineCap(Nothing, capPath)
' Create a copy of firstCap.
Dim secondCap As CustomLineCap = CType(firstCap.Clone(), _
CustomLineCap)
' Create a Pen object.
Dim pen As New Pen(Color.Black, 3F)
'Set up the line.
Dim point1 As New Point(20, 20)
Dim point2 As New Point(100, 100)
' Set up the caps.
pen.CustomStartCap = firstCap
pen.CustomEndCap = secondCap
' Draw the line and caps to the screen.
e.Graphics.DrawLine(pen, point1, point2)
End Sub
C#
private void CloneExample(PaintEventArgs e)
{
// Create a Path and add two lines to it,
// forming a custom line cap.
Point[] points =
{
new Point(-5, -5),
new Point(0, 0),
new Point(5, -5)
};
GraphicsPath capPath = new GraphicsPath();
capPath.AddLines(points);
// Create a CustomLineCap object.
CustomLineCap firstCap = new CustomLineCap(null, capPath);
// Create a copy of firstCap.
CustomLineCap secondCap = (CustomLineCap)firstCap.Clone();
// Create a Pen object.
Pen pen = new Pen(Color.Black, 3.0f);
// Set up the line.
Point point1 = new Point(20, 20);
Point point2 = new Point(100, 100);
// Set up the caps.
pen.CustomStartCap = firstCap;
pen.CustomEndCap = secondCap;
// Draw the line and caps to the screen.
e.Graphics.DrawLine(pen, point1, point2);
