ASP .Net Web API downloading images as binary

You can set the response content to a StreamContent object:

        var fileStream = new FileStream(path, FileMode.Open);        var resp = new HttpResponseMessage()        {            Content = new StreamContent(fileStream)        };        // Find the MIME type        string mimeType = _extensions[Path.GetExtension(path)];        resp.Content.Headers.ContentType = new MediaTypeHeaderValue(mimeType);

While this has been marked as answered, it wasn't quite what I wanted, so I kept looking. Now that I've figured it out, here's what I've got:

public FileContentResult GetFile(string id){    byte[] fileContents;    using (MemoryStream memoryStream = new MemoryStream())    {        using (Bitmap image = new Bitmap(WebRequest.Create(myURL).GetResponse().GetResponseStream()))            image.Save(memoryStream, ImageFormat.Jpeg);        fileContents = memoryStream.ToArray();    }    return new FileContentResult(fileContents, "image/jpg");}

Granted, that's for getting an image through a URL. If you just want to grab an image off the file server, I'd imagine you replace this line:

using (Bitmap image = new Bitmap(WebRequest.Create(myURL).GetResponse().GetResponseStream()))

With this:

using (Bitmap image = new Bitmap(myFilePath))

EDIT: Never mind, this is for regular MVC. for Web API, I have this:

public HttpResponseMessage Get(string id){    string fileName = string.Format("{0}.jpg", id);    if (!FileProvider.Exists(fileName))        throw new HttpResponseException(HttpStatusCode.NotFound);    FileStream fileStream = FileProvider.Open(fileName);    HttpResponseMessage response = new HttpResponseMessage { Content = new StreamContent(fileStream) };    response.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpg");    response.Content.Headers.ContentLength = FileProvider.GetLength(fileName);    return response;}

Which is quite similar to what OP has.

I did this exact thing. Here is my code:

if (!String.IsNullOrWhiteSpace(imageName))                {                    var savedFileName = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, Path.Combine(uploadPath, imageName));                    var image = System.Drawing.Image.FromFile(savedFileName);                    if (ImageFormat.Jpeg.Equals(image.RawFormat))                    {                        // JPEG                        using(var memoryStream = new MemoryStream())                        {                            image.Save(memoryStream, ImageFormat.Jpeg);                            var result = new HttpResponseMessage(HttpStatusCode.OK)                                {                                    Content = new ByteArrayContent(memoryStream.ToArray())                                };                            result.Content.Headers.ContentType = new MediaTypeHeaderValue("image/jpeg");                            result.Content.Headers.ContentLength = memoryStream.Length;                            return result;                        }                    }                    else if (ImageFormat.Png.Equals(image.RawFormat))                    {                        // PNG                        using (var memoryStream = new MemoryStream())                        {                            image.Save(memoryStream, ImageFormat.Png);                            var result = new HttpResponseMessage(HttpStatusCode.OK)                            {                                Content = new ByteArrayContent(memoryStream.ToArray())                            };                            result.Content.Headers.ContentType = new MediaTypeHeaderValue("image/png");                            result.Content.Headers.ContentLength = memoryStream.Length;                            return result;                        }                    }                    else if (ImageFormat.Gif.Equals(image.RawFormat))                    {                        // GIF                        using (var memoryStream = new MemoryStream())                        {                            image.Save(memoryStream, ImageFormat.Gif);                            var result = new HttpResponseMessage(HttpStatusCode.OK)                            {                                Content = new ByteArrayContent(memoryStream.ToArray())                            };                            result.Content.Headers.ContentType = new MediaTypeHeaderValue("image/gif");                            result.Content.Headers.ContentLength = memoryStream.Length;                            return result;                        }                    }                }

And then on the client:

                    var client = new HttpClient();                    var imageName = product.ImageUrl.Replace("~/Uploads/", "");                var path = Path.Combine(AppDomain.CurrentDomain.BaseDirectory,                                        Properties.Settings.Default.DeviceMediaPath + "\\" + imageName);                var response =                    client.GetAsync(apiUrl + "/Image?apiLoginId=" + apiLoginId + "&authorizationToken=" + authToken +                                    "&imageName=" + product.ImageUrl.Replace("~/Uploads/","")).Result;                if (response.IsSuccessStatusCode)                {                    var data = response.Content.ReadAsByteArrayAsync().Result;                    using (var ms = new MemoryStream(data))                    {                        using (var fs = File.Create(path))                        {                            ms.CopyTo(fs);                        }                    }                    result = true;                }                else                {                    result = false;                    break;                }
