WinForm 窗体与窗体相互嵌套

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：是否为顶级窗口，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();        }    }
