c# - IFormFile IEnumerable 的大小为 1，即使指定了多个文件上传

模型

    public List<ZertifikatFiles> Files { get; set; }

    [NotMapped]
    public IEnumerable<IFormFile> Certificates { get; set; }

查看

<form asp-action="AddCertificate" method="post" enctype="multipart/form-data"  data-file-dragndrop>
<div class="row">
    <div class="col-md-3"></div>
    <div class="form-group col-md-9">
        <input type="file" asp-for="IFormFiles" multiple />
        <span asp-validation-for="IFormFiles" class="text-danger"></span>
    </div>
</div>  </form>

Controller

[HttpPost]
    [ValidateAntiForgeryToken]
    public async Task<IActionResult> AddCertificate(Certificates certificates )
    {
        if (ModelState.IsValid)
        {
            if (certificates.IFormFiles != null && !certificates.IFormFiles.IsEmpty())
            {
                certificates.Files = new List<CertificateFiles>();
                foreach (IFormFile formFile in certificates.IFormFiles)
                {
                    byte[] bytes = new byte[formFile.Length];
                    using (var reader = formFile.OpenReadStream())
                    {
                        await reader.ReadAsync(bytes, 0, (int)formFile.Length);
                    }......

每当我尝试上传多个文件时，IEnumerable 只会获取第一个文件而将其余文件留在后面。
