OperatingSystem..::.Clone メソッド

更新 : 2007 年 11 月

このインスタンスと同一の OperatingSystem オブジェクトを作成します。

名前空間 : System
アセンブリ : mscorlib (mscorlib.dll 内)

構文

Visual Basic (宣言)

Public Function Clone As Object

Visual Basic (使用法)

Dim instance As OperatingSystem
Dim returnValue As Object

returnValue = instance.Clone()

public Object Clone()

Visual C++

public:
virtual Object^ Clone() sealed

public final Object Clone()

JScript

public final function Clone() : Object

戻り値

型 : System..::.Object
インスタンスのコピーである OperatingSystem オブジェクト。

実装

ICloneable..::.Clone()()()

例

Clone メソッドを使用して、OperatingSystem オブジェクトのコピーを作成するコード例を次に示します。クローンと元のオブジェクトは比較され、同じオブジェクトではないことが示されます。
