OperatingSystem.Clone 方法

定義

命名空間:

System

組件:

System.Runtime.dll

來源:

OperatingSystem.cs

建立與這個執行個體相同的 OperatingSystem 物件。

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

public object Clone ();

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

Public Function Clone () As Object

傳回

Object

OperatingSystem 物件，即這個執行個體的複本。

實作

Clone()

範例

下列程式碼範例說明如何使用 Clone 方法來建立 物件的複本 OperatingSystem 。 複製品會與原始物件進行比較，以顯示它們不是相同的物件。

   // parameters as opCreate1.

   // Clone opCreate1 and copy the opCreate1 reference.
   OperatingSystem^ opClone = safe_cast<OperatingSystem^>(opCreate1->Clone());
   OperatingSystem^ opCopy = opCreate1;
   
   // Compare the various objects for equality.
