栗子是 调用WIn32API 让窗口最前 

后台代码

        [DllImport("user32.dll")]



        private static extern bool SetForegroundWindow(IntPtr hWnd);



 



        // 




        Process process = null;



        private void OPenButton_Click(object sender, RoutedEventArgs e)




        {



            process = new Process();



            process.StartInfo.FileName = "iexplore.exe";



            process.StartInfo.Arguments = Text_Path.Text;



            process.Start();



        }



 



        private void TOPButton_Click(object sender, RoutedEventArgs e)




        {



            if (process != null)



            {



                var ptr = process.MainWindowHandle;



                SetForegroundWindow(ptr);



            }



        }



 



        private void FlushButton_Click(object sender, RoutedEventArgs e)




        {



            if (process != null)



            {



                var ptr = process.MainWindowHandle;



                SetForegroundWindow(ptr);



                SendKeys.SendWait("{F5}");



            }



        }

前台

    




        "Text_Path"  HorizontalAlignment="Left" Height="25" Margin="0,34,0,0" TextWrapping="Wrap" Text="https://www.baidu.com" VerticalAlignment="Top" Width="251"  />




        "OPenButton" Content="打开" HorizontalAlignment="Left" Margin="10,86,0,0" VerticalAlignment="Top" Width="75" Click="OPenButton_Click"/>




        "TOPButton" Content="前台" HorizontalAlignment="Left" Margin="10,123,0,0" VerticalAlignment="Top" Width="75" Click="TOPButton_Click"/>




        "FlushButton" Content="刷新" HorizontalAlignment="Left" Margin="10,160,0,0" VerticalAlignment="Top" Width="75" Click="FlushButton_Click"/>




 



    

  SendKeys.SendWait("{F5}"); 需要引用System.Windows.Forms.dll
