如何用WebApi返回对象的IEnumerable列表？

using System.Collections.Generic;
using System.Net.Http;
using System.Web.Http;

public class MyController : ApiController
{
    public HttpResponseMessage GetList()
    {
        // 从数据源获取IEnumerable列表
        IEnumerable<MyObject> myList = GetDataFromSource();

        // 将IEnumerable列表序列化为JSON格式
        string json = Newtonsoft.Json.JsonConvert.SerializeObject(myList);

        // 创建HttpResponseMessage对象并设置内容和响应头
        HttpResponseMessage response = new HttpResponseMessage();
        response.Content = new StringContent(json, System.Text.Encoding.UTF8, "application/json");

        return response;
    }

    private IEnumerable<MyObject> GetDataFromSource()
    {
        // 从数据源获取数据并返回IEnumerable列表
        // 这里仅作示例，实际情况需要根据具体需求进行实现
        List<MyObject> myList = new List<MyObject>();
        myList.Add(new MyObject { Id = 1, Name = "Object 1" });
        myList.Add(new MyObject { Id = 2, Name = "Object 2" });
        myList.Add(new MyObject { Id = 3, Name = "Object 3" });

        return myList;
    }
}

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