推荐答案

主表格

Main Form

namespace cp5
{
    public delegate void dHide(bool hide);
    public partial class MainForm : Form
    {
        public MainForm()
        {
            InitializeComponent();
        }
        void Button1Click(object sender, EventArgs e)
        {
            Form1 fm1=new Form1();
            fm1.delfunc+=hideform;
            fm1.Show();
        }
        void hideform(bool hide)
        {
            if (hide) this.Hide();
            else this.Show();
        }
    }
}

和子表单到隐藏/显示主窗体：

and child form to hide/show main form:

namespace cp5
{
	public partial class Form1 : Form
	{
		public dHide delfunc=null;
		public Form1()
		{
			InitializeComponent();
		}
		void Button1Click(object sender, EventArgs e)
		{
			delfunc(true);
		}
		void Button2Click(object sender, EventArgs e)
		{
			delfunc(false);	
		}		
	}
}
