如何将gridview列绑定到子类值？

public class Person
{
    public string Name { get; set; }
    public int Age { get; set; }
}

   <GridView.Columns>
       <GridViewColumn Header="Name">
           <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Name}" />
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
       <GridViewColumn Header="Age">
           <GridViewColumn.CellTemplate>
                <DataTemplate>
                    <TextBlock Text="{Binding Age}" />
                </DataTemplate>
            </GridViewColumn.CellTemplate>
        </GridViewColumn>
    </GridView.Columns>
</GridView>
