C＃WPF获取动态创建的图像子ID

Question

我有2种方法。一个动态创建图像，另一个动态删除图像。第一种方法一切正常。在第二种方法中，如果我指定要删除图像的位置（RemoveAt（）），它也会起作用。我知道该图像是用ID 13创建的。是否有任何方法可以动态获取var m的ID？谢谢。

private static void CreateImage ( double imageWidth, double imageHeight, double xPos, double yPos, string imageSource, string imageName)
    {
        m = new Image();

        mainWindow main = Application.Current.Windows[0] as mainWindow;
        main.mainGrid.Children.Add(m);
        m.Height = imageHeight; //Image height
        m.Width = imageWidth;//Image width
        //Width conversion to X
        double halfWidth = main.Width;
        double w = ( -halfWidth + xPos + imageWidth ) ;
        Convert.ToInt32 ( Math.Round(w) );
        //Height conversion to Y
        double halfHeight = main.Height;
        halfHeight = -halfHeight;
        double h = ( halfHeight + yPos + imageHeight ) ;
        Convert.ToInt32 ( Math.Round(h) );
        m.Margin = new Thickness(w, h, 0, 0);//left, top, right, bottom
        m.Source = new BitmapImage(new Uri(@"Resources\" + imageSource + ".png", UriKind.Relative));
        m.Name = imageName;
    }
    private static void DestroyImage()
    {
        mainWindow main = Application.Current.Windows[0] as mainWindow;
        main.mainGrid.Children.RemoveAt(m.);

    }
