控件大小随窗体改变（含字体）

为啥我跟着写出来是这个样子的？

重复看了也没发现原因

 public static class AutoSizeFormClass

  {

    public static float X;

    public static float Y;

    public static void setTag(Control cons)

    {

      foreach (Control con in cons.Controls)

      {

        con.Tag = cons.Width + ":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;

        if (con.Controls.Count>0)

        {

          setTag(con);

        }

      }

    }

    public static void setControls(float newx,float newy,Control cons)

    {

      foreach (Control con in cons.Controls)

      {

        if (con.Tag != null)

        {

          string[] mytag = con.Tag.ToString().Split(new char[] { ':' });

          float a = Convert.ToSingle(mytag[0]) * newx;

          con.Width = (int)a;

          a = Convert.ToSingle(mytag[1]) * newx;

          con.Height = (int)a;

          a=Convert.ToSingle(mytag[2]) * newx;

          con.Left= (int)a;

          a=Convert.ToSingle (mytag[3]) * newx;

          con.Top = (int)a;

          Single currentSize = Convert.ToSingle(mytag[4])*Math.Min(newx,newy);

          con.Font = new System.Drawing.Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);

          if (con.Controls.Count > 0)

          {

            setControls(newx, newy, con);

          }

        }

      }

    }

  }
