如何在.Net核心Web Api中上传目录？

using Microsoft.AspNetCore.Mvc;
using System.IO;
using System.Net.Http;
using System.Threading.Tasks;

[ApiController]
[Route("[controller]")]
public class UploadController : ControllerBase
{
    [HttpPost]
    public async Task<IActionResult> UploadDirectory([FromBody] string directoryPath)
    {
        string[] filePaths = Directory.GetFiles(directoryPath);

        foreach (string filePath in filePaths)
        {
            using (FileStream fileStream = System.IO.File.OpenRead(filePath))
            {
                using (HttpClient httpClient = new HttpClient())
                {
                    MultipartFormDataContent formData = new MultipartFormDataContent();
                    formData.Add(new StreamContent(fileStream), "file", Path.GetFileName(filePath));

                    HttpResponseMessage response = await httpClient.PostAsync("YOUR_UPLOAD_API_URL", formData);
                    response.EnsureSuccessStatusCode();
                }
            }
        }

        return Ok("Directory uploaded successfully.");
    }
}
