private float X;
    
    private float Y;
    
    private void  setTag(Control cons)
            {
                foreach (Control con in cons.Controls)
                {
                    con.Tag = con.Width +":" + con.Height + ":" + con.Left + ":" + con.Top + ":" + con.Font.Size;
                    if (con.Controls.Count > 0)
                        setTag(con);                
                }
            }
            private void setControls(float   newx, float  newy, Control  cons)
            {
                foreach (Control  con in cons .Controls )
                {
    
                    string[] mytag = con.Tag.ToString().Split(new char[] { ':' });
                    float a = Convert.ToSingle(mytag[0]) * newx;
                    con.Width = (int)a;
                    a=Convert.ToSingle(mytag[1]) * newy;
                    con.Height = (int)(a);
                    a=Convert.ToSingle(mytag[2]) * newx;
                    con.Left = (int)(a);
                    a=Convert.ToSingle(mytag[3]) * newy;
                    con.Top = (int)(a);
                    Single currentSize = Convert.ToSingle (mytag[4]) * Math.Min(newx,newy);
                    con .Font =new Font (con.Font .Name ,currentSize,con.Font .Style ,con.Font .Unit );
                    if(con.Controls .Count >0)
                    {
                        setControls (newx ,newy ,con );
                    }
                }
    
            }
    
            void Form1_Resize(object sender, EventArgs e)
            {
                float  newx = (this.Width )/ X;
                float newy = this.Height / Y;
                setControls(newx, newy, this);
                this.Text = this.Width.ToString() +" "+ this.Height.ToString();
    
            }

在Form_Load里面添加:

this.Resize += new EventHandler(Form1_Resize);    
      
    X = this.Width;    
    Y = this.Height;    
       
    
    setTag (this);  
    Form1_Resize(new object(),new EventArgs());//x,y可在实例化时赋值,最后这句是新加的，在MDI时有用
