控制器：

[HttpPost("CreateEmail")]
[Consumes("multipart/form-data")]
public async Task<ApiResponse<Guid>> PostEmailToProcess([FromForm]EmailToProcess email) 
{
    try
    {
        var emailToAdd = new EmailToProcessDto(email);
        emailToAdd.Created = DateTime.Now;

        var emailId = await _emailRepository.PostEmailAsync(emailToAdd);

        foreach (var file in email)
        {
            if (email.IFormFile != null)
            {
                await _contentUploadService.Upload(file, emailId.Data);
            }
        }
// etc

通过电子邮件发送到进程对象：

public class EmailToProcess
{
    public string From { get; set; }

    public string To { get; set; }

    ...

    public IFormFile[] IFormFile { get; set; }
}

当我发布EmailToProcess时-所有字段返回正确的数据，但IFormFile属性中的数据始终为空。当我允许它只提交1个IFormFile（无数组）时-它工作正常，没有空值
