C#放大窗体控件也随之改变

 private float x;//定义当前窗体的宽度
        private float y;//定义当前窗体的高度
        public SalesStatistics()
        {
            InitializeComponent();
            x = this.Width;
            y = this.Height;
            setTag(this);
        }

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)
                {

                }
            }
        }

        private void setControls(float newx, float newy, Control cons)
        {
            //遍历窗体中的控件，重新设置控件的值
            foreach (Control con in cons.Controls)
            {
                //获取控件的Tag属性值，并分割后存储字符串数组

                    //根据窗体缩放的比例确定控件的值
                    con.Width = Convert.ToInt32(System.Convert.ToSingle(mytag[0]) * newx);//宽度
                    con.Height = Convert.ToInt32(System.Convert.ToSingle(mytag[1]) * newy);//高度

                    Single currentSize = System.Convert.ToSingle(mytag[4]) * newy;//字体大小
                    con.Font = new Font(con.Font.Name, currentSize, con.Font.Style, con.Font.Unit);
                    if (con.Controls.Count > 0)
                    {

                    }
                }
            }
        }

窗体事件

 private void SalesStatistics_Resize(object sender, EventArgs e)
        {
            float newx = (this.Width) / x;
            float newy = (this.Height) / y;
            setControls(newx, newy, this);
        }
