How create a template XAML style (code behind) WPF

I have this code on my xaml and works fine (ListView component)

<ListView.ItemsPanel>
  <ItemsPanelTemplate>
    <StackPanel Orientation="Horizontal"></StackPanel>
  </ItemsPanelTemplate>

I´m trying to replicate on code behind using this answer Create DataTemplate in code behind, but i could not make it work (the Russell´s answer). Any help will be appreciated. Thanks!

Edit:

ListView listView = new ListView();
listView.ItemsPanel = GetItemsPanelTemplate();

private ItemsPanelTemplate GetItemsPanelTemplate()
{
  string xaml = @"<ItemsPanelTemplate   xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation' xmlns:x='http://schemas.microsoft.com/winfx/2006/xaml'>
                            <ListView.ItemsPanel>
                            <ItemsPanelTemplate>
                            <StackPanel Orientation=""Horizontal""></StackPanel>
                            </ItemsPanelTemplate>
                            </ListView.ItemsPanel>
                </ItemsPanelTemplate>";
  return XamlReader.Parse(xaml) as ItemsPanelTemplate;
}

Your code would work if you stripped out the ListView.ItemsPanel element and the inner ItemsPanelTemplate element:

private ItemsPanelTemplate GetItemsPanelTemplate()
{
    return XamlReader.Parse(
        @"<ItemsPanelTemplate xmlns='http://schemas.microsoft.com/winfx/2006/xaml/presentation'>
            <StackPanel Orientation='Horizontal' IsItemsHost='True' />
          </ItemsPanelTemplate>") as ItemsPanelTemplate;
}

However, the preferred way, based on the answer you linked, would be:

private ItemsPanelTemplate GetItemsPanelTemplate()
{
    var factory = new FrameworkElementFactory(typeof(StackPanel));

    factory.SetValue(StackPanel.OrientationProperty, Orientation.Horizontal);
    factory.SetValue(Panel.IsItemsHostProperty, true);

    return new ItemsPanelTemplate { VisualTree = factory };
}
