xamarin-在C＃中将带有跨度的子级添加到Grid元素时超出范围
(xamarin - Out of range when adding a child with a span to a Grid Element in C#)

我有这个代码。除了Grid.Add的第一行之外，所有网格元素均正常工作。
var grid = new Grid();
grid.ColumnSpacing = 4;
grid.RowSpacing = 8;
grid.Margin = 20;
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) });
grid.ColumnDefinitions.Add(new ColumnDefinition() { Width = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
grid.RowDefinitions.Add(new RowDefinition() { Height = new GridLength(1, GridUnitType.Star) });
grid.Children.Add(new BaseButton("A", "A"), 0, 2, 0, 0);
grid.Children.Add(new BaseButton("B", "B"), 0, 1);
grid.Children.Add(new BaseButton("C", "C"), 1, 1);
grid.Children.Add(new BaseButton("D", "D"), 0, 2);
grid.Children.Add(new BaseButton("E", "E"), 1, 2);
grid.Children.Add(new BaseButton("F", "F"), 0, 3);
grid.Children.Add(new BaseButton("G", "G"), 1, 3);
grid.Children.Add(new BaseButton("H", "H"), 2, 3);
该行：
grid.Children.Add(new BaseButton("A", "A"), 0, 2, 0, 0);
给我一个错误的说法：
System.ArgumentOutOfRangeException has been thrown. Specified argument was out of the range of valid values.
参数名称：底部
这是我需要实现的目标：
任何人都可以查看我所拥有的并评论可能存在的问题吗？
