使用上面的代码，我可以获得网格的第一个子节点（LayoutRoot）。但是我想通过它的行或列来获取网格子节点。我该怎么做。

Filter the Grid.Childrenbased on what Grid.GetRowand GetColumnreturns for every child.
Grid.Children根据每个孩子的内容Grid.GetRow和GetColumn回报过滤。
e.g.
例如
var itemsInFirstRow = LayoutRoot.Children
.Cast<UIElement>()
.Where(i => Grid.GetRow(i) == 0);
