C# 如何在带有4个标签的xamarin中使用2行2列将网格居中

我有一个两列两行的网格。我在网格的开始和结尾有堆栈布局，在布局中有4个标签，分别是grid.Row[0]grid.Column[0]。。。等等

守则：

如何将标签居中？

使用

标签上的
水平文本对齐=“中心”

<Frame CornerRadius="30"
       BackgroundColor="Transparent"
       Margin="20,0,20,10"
       HeightRequest="100"
       BorderColor="Red">
       <Grid BackgroundColor="Transparent"
              Padding="0,0,0,0">

                </Grid.RowDefinitions>
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*" />
                    <ColumnDefinition Width="*" />
