如何向我的接口(ASP.NET)发送2个object？

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

public class Address
{
    public string Street { get; set; }
    public string City { get; set; }
    public string Country { get; set; }
}

[Route("api/mycontroller")]
public class MyController : ApiController
{
    [HttpPost]
    public IHttpActionResult PostData([FromBody]Person person, [FromBody]Address address)
    {
        // 处理接收到的对象
        // 可以在这里进行业务逻辑处理、数据存储等操作
        // 返回适当的响应，例如：
        return Ok("数据已成功接收");
    }
}

using (HttpClient client = new HttpClient())
{
    // 设置请求的URL
    string url = "http://your-api-url/api/mycontroller";
    
    // 创建要发送的对象
    Person person = new Person { Name = "John", Age = 30 };
    Address address = new Address { Street = "123 Main St", City = "New York", Country = "USA" };
    
    // 将对象序列化为JSON字符串
    string personJson = JsonConvert.SerializeObject(person);
    string addressJson = JsonConvert.SerializeObject(address);
    
    // 构建请求内容
    var content = new StringContent(personJson + addressJson, Encoding.UTF8, "application/json");
    
    // 发送POST请求
    var response = await client.PostAsync(url, content);
    
    // 处理响应
    if (response.IsSuccessStatusCode)
    {
        // 请求成功
        string result = await response.Content.ReadAsStringAsync();
        Console.WriteLine(result);
    }
    else
    {
        // 请求失败
        Console.WriteLine("请求失败：" + response.StatusCode);
    }
}
