C# 根據桌面大小調整視窗大小

private void Form1_Load(object sender, EventArgs e)
        {
            int DeskWidth = Screen.PrimaryScreen.WorkingArea.Width; //PrimaryScreen為取得主顯示器，WorkingArea可取得顯示器的工作區(不包含工作列…等)
            int DeskHeight = Screen.PrimaryScreen.WorkingArea.Height;
            this.Width = Convert.ToInt32(DeskWidth * 0.8);
            this.Height = Convert.ToInt32(DeskHeight * 0.8);
        }
