当前form窗体随系统屏幕变化

 private void 新建_Load(object sender, EventArgs e)
        {

            int DeskWidth = Screen.PrimaryScreen.WorkingArea.Width;
            int DeskHeight = Screen.PrimaryScreen.WorkingArea.Height;
            this.Width = Convert.ToInt32(DeskWidth * 0.6);
            this.Height = Convert.ToInt32(DeskHeight * 0.6);
            this.StartPosition = FormStartPosition.CenterParent;
          }

设置的新建窗体是系统屏幕的0.6倍
