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()
C#
public Object Clone()
Visual C++
public:
virtual Object^ Clone() sealed
J#
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。
