如果您测试下面的代码和任何明亮的图像，您将看到 4 列和 4 行绘制在使用的图像上。我需要这个配置来达到某种效果。基本上我做到了，它可以工作，但是我想删除这些网格线，但不知道如何删除。它可能与 Grid 控件本身的实现有关吗？Grid 的属性 ShowGridlines 为 false。

有可能使用画布而不是网格并手动进行放置，但我想保留网格并将画布用作最后的解决方案。

您可以将RenderOptions.EdgeMode属性设置为Aliasedon Grid 以避免这种影响：

<VisualBrush x:Name="DissolveInBrush" TileMode="None" >
    <VisualBrush.Visual>
        <Grid RenderOptions.EdgeMode="Aliased">
            ...
        </Grid>
    </VisualBrush.Visual>
</VisualBrush>
