c#动态创建了一组按钮如何在按钮打开的界面显示点击按钮的名称

Question

            for (int i = 0; i<num; i++)
            {
                foreach (Form frm in Application.OpenForms)
                {
                    if (frm.Name == "main")
                    {
                        Button btn = new Button();
                        btn.Name =Convert.todtring(i);
                        btn.Size = new System.Drawing.Size(72, 76);
                        btn.Click += new EventHandler(btn_Click);
                        frm.Controls.Add(btn);
                        break;
}}}
        private void btn_Click(object sender, EventArgs e)
        {
            //throw new NotImplementedException();           
            begindesk.Fbegindesk fbgdesk = new foodmanager.begindesk.Fbegindesk(); 
            //fbgdesk.MdiParent = this;
            fbgdesk.Show();
            fbgdesk.Location = new System.Drawing.Point(350, 150);        }
现在我点击按钮出现了一个界面，如何在新的界面中获取这个按钮的名称呢！
    

Answer 1

begindesk.Fbegindesk fbgdesk = new foodmanager.begindesk.Fbegindesk(btn.name); 然后再在fbgdesk 的构造函数里保存btn.name这个值，这时你想怎样就怎样

Answer 2

begindesk.Fbegindesk fbgdesk = new foodmanager.begindesk.Fbegindesk(btn.name); 
上面怎么不能用红色，是这句
