如何从BitmapImage创建一个NotifyIcon

我有一个资源项目(png文件)在我的资源字典，我在几个地方使用。现在我想用它作为应用程序的NotifyIcon。但我不知道该怎么做。你有什么想法吗?

// my image:
var bitmap = new BitmapImage();
bitmap.UriSource = new Uri("pack://application:,,,/MyProj.Resources;component/Icons/Logo_48x48.png");
// and I try to do this:
var iconHandle = bitmap.GetHicon(); // but this line doesn't work
var ni = new NotifyIcon {
    Icon = System.Drawing.Icon.FromHandle(iconHandle),
    Visible = true
};

var sri = Application.GetResourceStream(
    new Uri("pack://application:,,,/MyProj.Resources;component/Icons/Logo_48x48.png"));
var bitmap = new Bitmap(sri.Stream);
var handle = bitmap.GetHicon();
var ni = new NotifyIcon {
    Icon = System.Drawing.Icon.FromHandle(handle),
    Visible = true
};
