递归遍历winForm 上所有控件

  public void findControls(Control control)
        ...{
            foreach (Control c in control.Controls)
            ...{
                string cType = c.GetType().Name;
                switch (cType)
                ...{
                    case "TextBox":
                        ((TextBox)c).Text = "ss";
                        break;
                    case "ComboBox":
                        ((ComboBox)c).Text = "";
                        break;
                }
                if (c.Controls.Count > 0)
                ...{
                    findControls(c);
                }
