如何从Listbox.SelectedItem获取数据源的不同成员

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

// 在某个方法中设置ListBox的数据源
List<Person> people = new List<Person>
{
    new Person { Name = "Alice", Age = 30 },
    new Person { Name = "Bob", Age = 25 },
    new Person { Name = "Charlie", Age = 35 }
};

listBox.ItemsSource = people;
listBox.DisplayMemberPath = "Name"; // 设置显示的字段

// 获取选中的Person对象的不同成员
private void GetSelectedItemDetails()
{
    Person selectedPerson = listBox.SelectedItem as Person;
    if (selectedPerson != null)
    {
        string name = selectedPerson.Name;
        int age = selectedPerson.Age;
        // 这里可以处理获取到的name和age
        Console.WriteLine($"Name: {name}, Age: {age}");
    }
    else
    {
        // 处理没有选中项的情况
        Console.WriteLine("No item selected.");
    }
}
