winform 自由縮放

最外層用panel,dock->Fill
建構函式:
GetAllInitInfo(this.Controls[0]);
#region 控制元件縮放
double formWidth;//窗體原始寬度double formHeight;//窗體原始高度
double scaleX;//水平縮放比例
double scaleY;//垂直縮放比例
Dictionary<string, string> controlInfo = new Dictionary<string, string>();//控制元件中心Left,Top,控制元件Width,控制元件Height,控制元件字型Size
/// <summary>
/// 獲取所有原始資料
/// </summary>

if ((item as UserControl) == null && item.Controls.Count > 0)
GetAllInitInfo(item);
}
}
private void ControlsChangeInit(Control CrlContainer)
