将子控件添加到WrapPanel

XAML:

<Window x:Class="WpfTestBench.PanelSample"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="PanelSample"  >
    <Grid>
        <WrapPanel Name="MyPanel" />
    </Grid>
</Window>

代码隐藏:

using System.Windows;
using System.Windows.Media;
using System.Windows.Shapes;

namespace WpfTestBench
{
    public partial class PanelSample
    {
        public PanelSample()
        {
            InitializeComponent();

            for (var i = 0; i < 5; i++)
            {
                MyPanel.Children.Add(new Rectangle
                {
                    Width = 100,
                    Height = 20,
                    StrokeThickness = 1,
                    Stroke = new SolidColorBrush(Colors.Black),
                    Margin = new Thickness(5)
                });
            }
        }
    }
}

执行结果:
