只要将要被潜逃的的窗体的TopLeve设置为Flase即可像普通的控件一样，被添加到另外一个窗体中，TopLeve：是否为*窗口，下面来看代码：

public partial class TTForm : Form

    {

        public TTForm()

        {

            InitializeComponent();

            weiboOfSina weibo = new weiboOfSina();

            weibo.Dock = DockStyle.Fill;

            weibo.FormBorderStyle = FormBorderStyle.None;

            weibo.TopLevel = false;

            this.Controls.Clear();

            this.Controls.Add(weibo);

            weibo.Show();

        }

    }
