Voorbeelden

Het volgende codevoorbeeld illustreert het gebruik van de Clone methode om een kopie van een OperatingSystem object te maken. De kloon wordt vergeleken met het oorspronkelijke object om aan te geven dat ze niet hetzelfde object zijn.

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

class CloneCompareDemo
{
    // Copy, clone, and duplicate an OperatingSystem object.
    static void CopyOperatingSystemObjects( )
    {
        // The Version object does not need to correspond to an
        // actual OS version.
        Version verMMBVer = new Version( 5, 6, 7, 8 );

        OperatingSystem opCreate1 = new
            OperatingSystem( PlatformID.Win32NT, verMMBVer );

        // Create another OperatingSystem object with the same
        // parameters as opCreate1.
        OperatingSystem opCreate2 = new
            OperatingSystem( PlatformID.Win32NT, verMMBVer );

        // Clone opCreate1 and copy the opCreate1 reference.
        OperatingSystem opClone =
            (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 ) );
    }

    static void Main( )
    {
        Console.WriteLine(
            "This example of OperatingSystem.Clone( ) " +
            "generates the following output.\n" );
        Console.WriteLine(

            "returns true only when both " +
            "references refer to the same object.\n" );

        CopyOperatingSystemObjects( );
    }
}
