WPF中Button参数传递有关问题

WPF中Button参数传递问题
在代码中用for循环new出了若干个button，这些button共用一个事件Img_Click，
但现在我用Img_Click能够实现多个事件的switch，请问各位大侠请问这个参数怎么传递？
代码如下：

private void Img_Click(object sender, RoutedEventArgs e) {
            Button btn = (Button)sender;
            
            DetailsImage(CrossRoadState.南丁字路口.ToString());
        }

        private void ComboBox_SelectionChanged(object sender, SelectionChangedEventArgs e) {
            DataGridIntro.CrossingArray _CrossingArray = new DataGridIntro.CrossingArray();
            int index = Convert.ToInt32(cmb.SelectedValue)-1;

            if (index >= _CrossingArray.Count || index == -2) return;
            CrossRoadPixture.Children.Clear();
            for (int i = 0; i < Ceiling(_CrossingArray[index].Count); i++) {
                StackPanel _StackPanel = new StackPanel();
                _StackPanel.Orientation = Orientation.Horizontal;
                _StackPanel.Margin = new Thickness(10, 10, 0, 10);
                for (int j = 0; j < 2; j++) {
                    if (i * 2 + j >= _CrossingArray[index].Count) break;
                    StackPanel _InStackPanel = new StackPanel();
                    _InStackPanel.Orientation = Orientation.Vertical;
                    _InStackPanel.Margin = new Thickness(10, 10, 0, 10);
                    Button _Button = new Button();
                    _Button.Click += new RoutedEventHandler(Img_Click);

                    StackPanel _StackOnButton = new StackPanel();
                    BitmapImage imageBitmap = new BitmapImage(new Uri(_CrossingArray[index][i*2+j].ImagePath, UriKind.Absolute));

                    Image _Image = new Image();
