原文:WPF 精修篇 调用Win32Api

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

    <Grid>





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





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





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





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





 





    </Grid>

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