Make http client synchronous: wait for response

Question

I have some file to upload and some of the files failed because the post is asynchronous and not synchronous..

I\'m trying to make this call as synchronized call..

Answer 1

change

await content.ReadAsStringAsync().ConfigureAwait(false)

to

content.ReadAsStringAsync().Result

the ReadAsStringAsync returns a Task object. the '.Result' in the end of the line tell the compiler to return the inner string.

Answer 2

That should do it:

static async Task<JObect> Upload(string key, string url, string 
                             sourceFile, string targetFormat)
{ 
    using (HttpClientHandler handler = new HttpClientHandler { 
                                           Credentials = new NetworkCredential(key, "") 
                                   })
    using (HttpClient client = new HttpClient(handler))
    {
         var request = new MultipartFormDataContent();
         request.Add(new StringContent(targetFormat), "target_format");
         request.Add(new StreamContent(File.OpenRead(sourceFile)),
                                   "source_file",
                                    new FileInfo(sourceFile).Name);

        using (HttpResponseMessage response = await client.PostAsync(url,request))

        using (HttpContent content = response.Content)
        {
            string data = await content.ReadAsStringAsync();
            return JsonObject.Parse(data);
        }
    }
}
