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
