Upload Image using PostAsync RRS feed

  • Question

  • Hi,

    I would like to upload an image from my project to my web service. Here is my code:

    byte[] fileBytes;
    
    using (var fileStream = await imageEditor.GetStream())
    {
        var binaryReader = new BinaryReader(fileStream);
    
        fileBytes = binaryReader.ReadBytes((int)fileStream.Length);
    }
    
    var imageBinaryContent = new ByteArrayContent(fileBytes);
    
    var multipartContent = new MultipartFormDataContent();
    multipartContent.Add(imageBinaryContent, "image");
    

    and my PostAsync is like this:

    var client = new HttpClient();
    client.BaseAddress = new Uri("https://my.domain.com/api/save_data.php");
    
    client.DefaultRequestHeaders.Accept.Clear();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    
    var content = new FormUrlEncodedContent(new[]
    {
        new KeyValuePair<string, string>("image", IMAGE_DATA_COMES_HERE)
    });
    
    var response = await client.PostAsync("https://my.domain.com/api/save.php", content);
    

    How can I put the image into my PostAsync in order to upload to my PHP web service?

    Thanks,

    Jassim

  • Hi Jassim Rahma,

    Thank you for posting here.

    According to your question, I have found two related references.

    1. Upload image using HttpClient
    2. Upload an image via httpclient

    Hope them can help you.

    Best Regards,
