Answer 1

父窗体：
myFrm child = new myFrm (); //生成子窗体实例
this.panel1.Controls.Clear();
this.panel1.Controls.Add(child);//将子窗体放到panel1中
child.Show();//显示子窗体

子窗体构造函数
public myFrm ()
{
InitializeComponent();
this.TopLevel = false; //设置子窗体为非顶级窗体
this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.None;//去掉子窗体边框
}

Answer 2

通过SetParent嵌入实现！
例子：
[DllImport("user32.dll", EntryPoint = "SetParent")]
public static extern int SetParent(IntPtr hWndChild, IntPtr hWndNewParent);

MDIParent1 form = new MDIParent1();
SetParent(form.Handle, this.Panel1.Handle);
form.Location = new Point(0, 0);
form.Size = this.Size;
form.Show();
