如何在Xamarin表单中将图像放在一行内的每一列中？

Grid grid = new Grid();
grid.RowDefinitions.Add(new RowDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());
grid.ColumnDefinitions.Add(new ColumnDefinition());

Image image1 = new Image();
image1.Source = "image1.png";
Grid.SetRow(image1, 0);
Grid.SetColumn(image1, 0);

Image image2 = new Image();
image2.Source = "image2.png";
Grid.SetRow(image2, 0);
Grid.SetColumn(image2, 1);

Image image3 = new Image();
image3.Source = "image3.png";
Grid.SetRow(image3, 0);
Grid.SetColumn(image3, 2);

grid.Children.Add(image1);
grid.Children.Add(image2);
grid.Children.Add(image3);

Content = new StackLayout
{
    Children = { grid }
};
