c# - 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。

我已经阅读了这篇文章......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

和我得到的 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 )
{

}

看起来您需要VideoDirectoryProperty像您的 VB 代码所说的那样定义为静态的Shared。

你也有GetType(WebCam)VB 但typeof(WCam)在 C# 中。

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)
{

}
