Creates an OperatingSystem object that is identical to this instance.

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

public object Clone();

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

Public Function Clone () As Object

Returns

Object

An OperatingSystem object that is a copy of this instance.

Implements

Clone()

Examples

The following code example illustrates the use of the Clone method to make a copy of an OperatingSystem object. The clone is compared with the original object to show that they are not the same object.

// Example for the OperatingSystem::Clone method.
using namespace System;

// Copy, clone, and duplicate an OperatingSystem object.
void CopyOperatingSystemObjects()
{
   
   // The Version object does not need to correspond to an 
   // actual OS version.
   Version^ verMMBVer = gcnew Version( 5,6,7,8 );
   OperatingSystem^ opCreate1 = gcnew OperatingSystem( PlatformID::Win32NT,verMMBVer );
   
   // Create another OperatingSystem object with the same 
   // parameters as opCreate1.
   OperatingSystem^ opCreate2 = gcnew OperatingSystem( PlatformID::Win32NT,verMMBVer );
   
   // Clone opCreate1 and copy the opCreate1 reference.
   OperatingSystem^ opClone = safe_cast<OperatingSystem^>(opCreate1->Clone());
   OperatingSystem^ opCopy = 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?", opCreate1->Equals( opClone ) );
   Console::WriteLine( "{0,-50}{1}", "Is the copied object the same as the original?", opCreate1->Equals( opCopy ) );
}

int main()
{
   Console::WriteLine( "This example of OperatingSystem::Clone( ) "
   "generates the following output.\n" );
   Console::WriteLine( "Create an OperatingSystem object, and then "
   "create another object with the \n"
   "same parameters. Clone and copy the original "
   "object, and then compare \n"
   "each object with the original "
   "using the Equals( ) method. Equals( ) \n"
   "returns true only when both "
   "references refer to the same object.\n" );
   CopyOperatingSystemObjects();
}
