C#控件随窗体大小变化

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
