图像正在从顶部切割，因为它们被放置在底部

我在vb.net wpf中遇到问题。我想在一个工具中做一些捐赠页面的工作，我们在那里可以捐献多种想法。你也应该能够评估捐赠的想法。因此我创建了显示评分的星星。图像正在从顶部切割，因为它们被放置在底部

问题是星星的前2行显示正确。但是第三个从最低处消失。

请参阅我们使用（当然我们这样做只是在我们的空闲时间和代码尝试学习对我们自己的。therefroe请不要介意，这个代码可能不是你所见过的最好的 - 我们只是很高兴，它正在更多或更少）：

      DonationGrid.Children.Add(Starimage_right_3) 
      DonationGrid.Children.Add(Starimage_right_4) 
      DonationGrid.Children.Add(Starimage_right_5) 

      Me.Height = Starimage_left_1.Margin.Top + 26 + 25 + 10 
      DonationGrid.Height = Me.Height + 200 

      OpenDonations -= 1 
      i += 1 
      heightvalue += 205 

     Loop 

     Me.AddChild(DonationGrid) 

    Catch 
    End Try 

End Sub 
End Class

这是该窗口的XAML：

代码中的“Z”是什么？ –

z只是一个从1开始并在循环中计数的整数。我使用它为我创建的不同对象提供唯一的名称。此外，我用它来确定第一个循环来获得正确的窗口大小。在代码中它也用于边缘 - 这仅仅用于测试星星消失的地方。 –

我解决了这个问题。我刚创建了一些新图片并使用它们。我不知道为什么旧的starimages不起作用，但新的它正在按预期工作。
