WPF 精修篇 调用Win32Api

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
