使用HttpClient PostAsJsonAsync调用我的接口，如何正确接受接口中的复杂类型？

using System;
using System.Net.Http;
using System.Net.Http.Headers;
using Newtonsoft.Json;

public class MyComplexType
{
    public string Name { get; set; }
    public int Age { get; set; }
    // 其他属性...
}

public class Program
{
    public static async Task Main(string[] args)
    {
        var complexType = new MyComplexType
        {
            Name = "John",
            Age = 25
            // 设置其他属性...
        };

        var json = JsonConvert.SerializeObject(complexType);
        var content = new StringContent(json);
        content.Headers.ContentType = new MediaTypeHeaderValue("application/json");

        using (var client = new HttpClient())
        {
            var response = await client.PostAsJsonAsync("http://example.com/api/myendpoint", content);
            var responseContent = await response.Content.ReadAsStringAsync();

            var result = JsonConvert.DeserializeObject<MyComplexType>(responseContent);
            // 处理返回的复杂类型对象...
        }
    }
}
