Description Valentin Polushkin 2014-08-08 13:01:47 UTC
Customer reports the following:

"I had a problem trying to send a multi-part request using http client. Basically as far as i could figure out it came down to xamarin's implementation of NameValueHeaderValue not allowing quotes in the key / values. This code worked in a c# .net 4.5, but the same code threw a format exception when run in PCL in my project."

using (var content = new MultipartFormDataContent())
{
    string filename = Guid.NewGuid().ToString() + ".png";
    content.Add(new StringContent(filename), "\"name\"");
    var imageContent = new ByteArrayContent(image.ImageBytes);
    imageContent.Headers.ContentDisposition = new ContentDispositionHeaderValue("form-data")
    {
        Name = "\"file\"",
        FileName = "\"" + filename + "\""
    };

    imageContent.Headers.ContentType = MediaTypeHeaderValue.Parse(image.MimeType);
    content.Add(imageContent);

    var postResult = await client.PostAsync(uri, content);

    if (!postResult.IsSuccessStatusCode)
        return "";
        
    weedId = await postResult.Content.ReadAsStringAsync();
