OperatingSystem.Clone 方法
创建与此实例相同的 OperatingSystem 对象。
**命名空间:**System
**程序集:**mscorlib（在 mscorlib.dll 中）
语法
声明
Public Function Clone As Object
用法
Dim instance As OperatingSystem
Dim returnValue As Object
returnValue = instance.Clone
public Object Clone ()
public:
virtual Object^ Clone () sealed
public final Object Clone ()
public final function Clone () : Object
返回值
OperatingSystem 对象，是此实例的副本。
示例
下面的代码示例演示如何使用 Clone 方法创建 OperatingSystem 对象的副本。复本与原始对象进行比较，以显示它们不是同一个对象。
' Example for the OperatingSystem.Clone method.
Imports System
Imports Microsoft.VisualBasic
Module CloneCompareDemo
' Copy, clone, and duplicate an OperatingSystem object.

' The Version object does not need to correspond to an
' actual OS version.

Dim opCreate1 As New _
OperatingSystem( PlatformID.Win32NT, verMMBVer )
' Create another OperatingSystem object with the same
' parameters as opCreate1.
Dim opCreate2 As New _
OperatingSystem( PlatformID.Win32NT, verMMBVer )
' Clone opCreate1 and copy the opCreate1 reference.
Dim opClone As OperatingSystem = _
CType( opCreate1.Clone( ), OperatingSystem )
Dim opCopy As OperatingSystem = opCreate1
' Compare the various objects for equality.
Console.WriteLine( "{0,-50}{1}", _
"Is the second object the same as the original?", _
opCreate1.Equals( opCreate2 ) )
Console.WriteLine( "{0,-50}{1}", _
"Is the object clone the same as the original?", _
