關於C# 窗口放大縮小窗口內控件等比例放大縮小

關於C# 窗口放大縮小窗口內控件等比例放大縮小   這種方法不是最好的  屬於重繪 比較慢，我本來的想法是等比例DPI轉化成百分比來調用SIZE參數完成，時間來不及了，先將就着用。

#region 控件跟隨窗體大小 float XY
        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();
 
        }
        #endregion
 
//使用方法
        private void Form1_Load(object sender, EventArgs e)
        {
            this.Resize += new EventHandler(Form1_Resize);
            X = this.Width;    
            Y = this.Height;    
            setTag(this);
            Form1_Resize(new object(), new EventArgs());
        }
