c# - 如何使用循环访问 C# 中的表单元素？

Question

  if(pictureBox1.Tag.ToString() == "accept")
        {
            char room1 = Convert.ToChar(lbl_roomid1.Text);
            row1[13] = (byte)room1;

            DateTime sdt1 = DateTime.Parse(txt_sdate1.Text);
            //some code
         }
  if (pictureBox2.Tag.ToString() == "accept")
        {
            char room2 = Convert.ToChar(lbl_roomid2.Text);
            row1[13] = (byte)room2;

            DateTime sdt1 = DateTime.Parse(txt_sdate2.Text);
            //some code
         }

/* 如果我想在循环中输入这段代码怎么办？？我需要为 10 个图片框做同样的事情 */

像这样:

    public void DoMagic(Label label, TextBox textBox)
    {
        //...
    }

还有这个:

        foreach (Control currentControl in this.Controls)
        {
            if (currentControl is PictureBox)
            {
                if (((PictureBox)currentControl).Tag.ToString().Equals("accept"))
                {
                    string controlId = currentControl.Name.Remove(0, 11);
                    string labelName = string.Concat("lbl_roomid", controlId);
                    string txtName = string.Concat("txt_sdate", controlId);

                    this.DoMagic(this.Controls.Find(labelName, true)[0] as Label, this.Controls.Find(txtName, true)[0] as TextBox);
                }
            }
        }
