从对象的属性中设置DataGrid中的单元格行值，但使用该属性来获取其他值？

<DataGrid AutoGenerateColumns="False">
    <DataGrid.Columns>
        <DataGridTextColumn Header="Name" Binding="{Binding Name}" />
        <DataGridTextColumn Header="Age" Binding="{Binding Age}" />
    </DataGrid.Columns>
</DataGrid>

List<Person> people = new List<Person>
{
    new Person { Name = "John", Age = 25 },
    new Person { Name = "Jane", Age = 30 },
    // 添加更多的Person对象
};

dataGrid.ItemsSource = people;

private void dataGrid_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
    if (dataGrid.SelectedItem is Person selectedPerson)
    {
        string name = selectedPerson.Name;
        int age = selectedPerson.Age;

        // 使用name和age来获取其他值
        // ...
    }
}
