C # Web.API Returned Image. MemoryStream & # 8594; StreamContent returns a browken image

Question

I need to return an image that is stored on disk from the web service.

In my controller, I perform some search operations and send the file. Here is my code.

public HttpResponseMessage Get([FromUri]ShowImageRequest req) { // ....................... // ....................... // load image file var imgStream = new MemoryStream(); using (Image image = Image.FromFile(fullImagePath)) { image.Save(imgStream, ImageFormat.Jpeg); } imgStream.Seek(0, SeekOrigin.Begin); // it does not work without this var res = new HttpResponseMessage(HttpStatusCode.OK); res.Content = new StreamContent(imgStream); res.Content.Headers.ContentType = new ediaTypeHeaderValue("image/jpeg"); return res; } 

If I do not add this line, I see in the length of the body of the response of the feedback 0

 imgStream.Seek(0, SeekOrigin.Begin); 

Otherwise, it works. What am I missing and why do I need it?

Answer 1

After saving the position of the stream at the end. This means that reading from it does not return bytes.

Everyone faces this exact problem once :)
