Examples

This code example is part of a larger example provided for the RegistryKey class.

// Delete or close the new subkey.
Console::Write( "\nDelete newly created registry key? (Y/N) " );
if ( Char::ToUpper( Convert::ToChar( Console::Read() ) ) == 'Y' )
{
   Registry::CurrentUser->DeleteSubKeyTree( "Test9999" );
   Console::WriteLine( "\nRegistry key {0} deleted.", test9999->Name );
}
else
{
   Console::WriteLine( "\nRegistry key {0} closed.", test9999->ToString() );
   test9999->Close();
}

// Delete or close the new subkey.
Console.Write("\nDelete newly created registry key? (Y/N) ");
if(Char.ToUpper(Convert.ToChar(Console.Read())) == 'Y')
{
    Registry.CurrentUser.DeleteSubKeyTree("Test9999");
    Console.WriteLine("\nRegistry key {0} deleted.",
        test9999.Name);
}
else
{
    Console.WriteLine("\nRegistry key {0} closed.",
        test9999.ToString());
    test9999.Close();
}

' Delete or close the new subkey.
Console.Write(vbCrLf & "Delete newly created " & _
    "registry key? (Y/N) ")
If Char.ToUpper(Convert.ToChar(Console.Read())) = "Y"C Then
    Registry.CurrentUser.DeleteSubKeyTree("Test9999")
    Console.WriteLine(vbCrLf & "Registry key {0} deleted.", _
        test9999.Name)
Else
    Console.WriteLine(vbCrLf & "Registry key {0} closed.", _
        test9999.ToString())
    test9999.Close()
End If

Remarks

Calling this method on system keys will have no effect, because system keys are never closed.

This method does nothing if you call it on an instance of RegistryKey that is already closed.
