其实Anchor和Dock属性也可以实现,但好象只对容器效果理想,而且字体大小也没有变化.最近论坛上有好多这样的贴子,具体实现代码如下:

        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]) * 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)
        {
           // throw new Exception("The method or operation is not implemented.");
            float  newx = (this.Width )/ X;
          //  float newy = (this.Height - this.statusStrip1.Height) / (Y - y);
            float newy = this.Height / Y;
            setControls(newx, newy, this);
            //this.Text = this.Width.ToString() +" "+ this.Height.ToString();

        }

然后在你窗体的构造函数InitializeComponent();下面添加: 

            this.Resize += new EventHandler(Form1_Resize); 

            X = this.Width; 
            Y = this.Height; 
            y = this.statusStrip1.Height; 
            setTag (this);

当然定义了两个全局变量,private float X; private float Y;

细心的你一定会发现还有个y ;这是因为如果有statusStrip1之类的控件,这是就一定要注意,窗体的实际宽度和高度一定要减去statusStrip1之类.

如果是容器,最好将Anchor和Dock属性也修改过来.

效果还不错.
