Public Property Child As Control

裝載的 Windows Forms 控制件。

例外狀況

ArgumentException

範例

下列程式代碼範例示範如何使用 Child 屬性，將裝載的控件新增至 WindowsFormsHost 元素。 如需詳細資訊，請參閱 逐步解說：在 WPF 中裝載 ActiveX 控制件。

private void Window_Loaded(object sender, RoutedEventArgs e) 
{
    // Create the interop host control.
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();

    // Create the ActiveX control.
    var axWmp = new WmpAxLib.AxWindowsMediaPlayer();

    // Assign the ActiveX control as the host control's child.
    host.Child = axWmp;

    // Add the interop host control to the Grid
    // control's collection of child controls.
    this.grid1.Children.Add(host);

    // Play a .wav file with the ActiveX control.
    axWmp.URL = @"C:\Windows\Media\tada.wav";
}

Private Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)

    ' Create the interop host control.
    Dim host As New System.Windows.Forms.Integration.WindowsFormsHost()

    ' Create the ActiveX control.
    Dim axWmp As New AxWMPLib.AxWindowsMediaPlayer()

    ' Assign the ActiveX control as the host control's child.
    host.Child = axWmp

    ' Add the interop host control to the Grid
    ' control's collection of child controls.
    Me.grid1.Children.Add(host)

    ' Play a .wav file with the ActiveX control.
    axWmp.URL = "C:\Windows\Media\tada.wav"

End Sub

備註

只能裝載一個子控件，但 Child 可以有任意數目的子系。

子控件不能是最上層窗體。

如果 Child 是 Form，則表單的 ControlBox 屬性會設定為 false。

XAML 值

物件 A WindowsFormsHost 專案（或可能的子類別）。

hostedControl 指定託管 Windows Forms 控件的 元素。 在標記中指定自定義控件通常需要 xmlns 對應，請參閱 WPF XAML 的 XAML 命名空間和命名空間對應。
