C# Winfrom 控件等比例放大的解决方案

Winfrom 控件跟随窗体大小变化而变化

 #region 窗体基本事件，这里需要根据自己的窗体设置相应事件
        /// <summary>
        /// 窗体加载事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void Form_Load(object sender, EventArgs e)
        {
            serverFrom = this;
            
            ChangeFormSize();//设置变化窗体大小
        }

        /// <summary>
        /// 窗体的 Resize 事件
        /// </summary>
        /// <param name="sender"></param>
        /// <param name="e"></param>
        private void From_Resize(object sender, EventArgs e)
        {
            float WidthChangeProportion = (this.Width) / CurrentWidth;//宽度变化比例
            float HeightChangeProportion = (this.Height) / CurrentHeight;//高度变化比例
            UpdateControlsSize(WidthChangeProportion, HeightChangeProportion, this);
