Ruang nama:

System.Drawing.Drawing2D

Rakitan:

System.Drawing.Common.dll

Paket:

System.Drawing.Common v8.0.0

Sumber:

GraphicsPath.cs

Membuat salinan yang tepat dari jalur ini.

public:
 virtual System::Object ^ Clone();

public object Clone ();

abstract member Clone : unit -> obj
override this.Clone : unit -> obj

Public Function Clone () As Object

Mengembalikan

Object

Metode GraphicsPath ini membuat, dilemparkan sebagai objek.

Penerapan

Clone()

Contoh

Contoh kode berikut dirancang untuk digunakan dengan Formulir Windows, dan memerlukan PaintEventArgse, OnPaint objek peristiwa. Kode melakukan tindakan berikut:

• Membuat jalur.

• Menambahkan beberapa gambar ke jalur.

• Menggambar jalur ke layar.

• Mengkloning salinan jalur itu.

• Menggambar jalur baru ke layar.

Perhatikan bahwa panggilan Clone metode harus dilemparkan sebagai GraphicsPath.
