将VB DependencyProperty转换为C＃

Question

我无法弄清楚如何将DependencyProperty的VB代码转换为C＃代码。

我已阅读this文章......但无论如何我需要一些帮助。

Public Shared VideoDirectoryProperty As DependencyProperty = _
DependencyProperty.Register("VideoDirectory", GetType(String), GetType(Webcam), _
                                        New FrameworkPropertyMetadata(New PropertyChangedCallback(AddressOf DirectoryChange)))

Private Shared Sub DirectoryChange(ByVal source As DependencyObject, ByVal e As DependencyPropertyChangedEventArgs)

End Sub

我得到了

和C＃代码：

public DependencyProperty VideoDirectoryProperty = DependencyProperty.Register("VideoDirectory", typeof(string), typeof(WCam), 
             new FrameworkPropertyMetadata(new PropertyChangedCallback(DirectoryChange)));

private void DirectoryChange(DependencyObject source, DependencyPropertyChangedEventArgs e )
{

}

Answer 1

您似乎需要将VideoDirectoryProperty定义为静态，因为您的VB代码是Shared。

此外，您在VB中有GetType(WebCam)但在C＃中有typeof(WCam)。

public static readonly DependencyProperty VideoDirectoryProperty =
    DependencyProperty.Register(
        "VideoDirectory",
        typeof(string),
        typeof(WebCam), 
        new FrameworkPropertyMetadata(new PropertyChangedCallback(DirectoryChange)));

private static void DirectoryChange(
    DependencyObject source, DependencyPropertyChangedEventArgs e)
{

}
