C# 指定弹出窗口位置

            messageForm messageform = new messageForm();//实例化窗体对象

            Point point = new Point(Screen.PrimaryScreen.WorkingArea.Width - messageform.Size.Width, Screen.PrimaryScreen.WorkingArea.Height - messageform.Size.Height);//窗体位置

            messageform.StartPosition = FormStartPosition.Manual;//窗体其实位置类型，manual由location指定

            messageform.Location = point;

            messageform.Show();
