using System.Windows.Forms;
using System.Windows.Forms.Integration;

    {
        public Form1()
        {
            InitializeComponent();

            ElementHost host = new ElementHost();
            host.Dock = DockStyle.Fill;
            this.Controls.Add(host);
        }
    }
}

调整表单大小时，您会在表单边框处看到两个黑色边缘:
