ASP Net Core Web API IFormFile到图像

Question

您好，我有服务器网络API

代码服务器端是

[HttpPost("Recognition")]
        public async Task<IActionResult> Recognition(IFormFile file)
    {
        if(file != null)
        {
            using (var ms = new MemoryStream())
            {
                file.CopyTo(ms);
                var fileBytes = ms.ToArray();

                var toImage = file.OpenReadStream();
                Image images = new Bitmap(toImage);

                string name = faceHandle.FindAndRecognize(images);

            }

我正在尝试将IFormFile转换为Image，连接System.Drawing;

ms有两个错误，它的'ms.ReadTimeout'引发了'System.InvalidOperationException'类型的异常。和|| “ ms.WriteTimeout”引发了类型为“ System.InvalidOperationException”的异常
