c# 如何得到窗口中控件的句柄
[img=http://][/img]我本人是搞C++的,C#的有些不太熟,
下面是一个简单的对话框的XAML,里面有个canvas和button1变量,我想得到这两个的句柄(HWND)

<Window x:Class="Traffic.AP.FocusSet"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        Title="调焦设置" FontSize="16" Height="500" Width="500" WindowStartupLocation="CenterScreen" ResizeMode="CanMinimize" Closing="Window_Closing" Loaded="Window_Loaded">
    <Grid>
        <Grid.RowDefinitions>
            <RowDefinition Height="370*" />
            <RowDefinition Height="91*" />
        </Grid.RowDefinitions>
        <Canvas Name="canvas" Grid.Row="0">
        </Canvas>
        <Button Content="抓拍" Grid.Row="1" Height="28" HorizontalAlignment="Left" Margin="147,22,0,0" Name="button1" VerticalAlignment="Top" Width="75" Click="button1_Click" />
    </Grid>
</Window>



类的代码如下,

namespace Traffic.AP
{
    /// <summary>
    /// Interaction logic for FocusSet.xaml
    /// </summary>
    public partial class FocusSet : Window
    {
        public FocusSet(delegateRecordFocus recordFocus,delegateGrabImg grabImg)
        {
            InitializeComponent();
            this.m_recordFocus = recordFocus;
            this.m_grabImg = grabImg;
        }

        public delegate void delegateRecordFocus(IntPtr hWndScreen, string tempDir, bool bStop);
        private delegateRecordFocus m_recordFocus;

        public delegate void delegateGrabImg();
        private delegateGrabImg m_grabImg;

        private void button1_Click(object sender, RoutedEventArgs e)
        {
            m_grabImg();
        }

        private void Window_Loaded(object sender, RoutedEventArgs e)
        {
            //var helper = new System.Windows.Interop.WindowInteropHelper(this);
