在ASP.NET中将类绑定到下拉列表

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

public class PersonService
{
    public List<Person> GetAllPersons()
    {
        // 这里应该是从数据库或其他数据源获取数据的逻辑
        return new List<Person>
        {
            new Person { Id = 1, Name = "Alice" },
            new Person { Id = 2, Name = "Bob" },
            new Person { Id = 3, Name = "Charlie" }
        };
    }
}

<asp:DropDownList ID="ddlPersons" runat="server"></asp:DropDownList>

protected void Page_Load(object sender, EventArgs e)
{
    if (!IsPostBack)
    {
        BindDropDownList();
    }
}

private void BindDropDownList()
{
    PersonService personService = new PersonService();
    List<Person> persons = personService.GetAllPersons();

    ddlPersons.DataSource = persons;
    ddlPersons.DataTextField = "Name";
    ddlPersons.DataValueField = "Id";
    ddlPersons.DataBind();
}
