如何将mvc中的datetime作为参数发送到web api？

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

public class HomeController : Controller
{
    public async Task<ActionResult> SendDateTime()
    {
        DateTime dateTime = DateTime.Now;
        string json = JsonConvert.SerializeObject(dateTime);

        using (HttpClient client = new HttpClient())
        {
            HttpContent content = new StringContent(json, Encoding.UTF8, "application/json");
            HttpResponseMessage response = await client.PostAsync("https://yourapi.com/api/datetime", content);

            if (response.IsSuccessStatusCode)
            {
                string result = await response.Content.ReadAsStringAsync();
                // 处理响应
            }
        }

        return View();
    }
}

using System;
using System.Net.Http;
using System.Threading.Tasks;
using Microsoft.AspNetCore.Mvc;
using Newtonsoft.Json;

[ApiController]
[Route("api/[controller]")]
public class DateTimeController : ControllerBase
{
    [HttpPost]
    public async Task<IActionResult> PostDateTime()
    {
        string requestBody = await new StreamReader(Request.Body).ReadToEndAsync();
        DateTime receivedDateTime = JsonConvert.DeserializeObject<DateTime>(requestBody);

        // 处理接收到的DateTime对象
        // ...

        return Ok();
    }
}
