  Hi ,

   

  It's a little bit dated, but I have this .Net example that I prepared a while back that should give you info on how to set up a sample app.

  those example didn't work.

  I explain:

  var task = Task.Run(

  async () =>
  {
  bool ret = false;
  BoxConfig config = new BoxConfig(CLIENTID, CLIENTSECRET, new Uri("http://127.0.0.1"));
  var session = new OAuthSession(APPTOKEN, "N/A", 3600, "bearer");
  var client = new BoxClient(config, session);

  using (FileStream fileStream = new FileStream(filePath, FileMode.Open))
  {
  BoxFileRequest requestParams = new BoxFileRequest()
  {
  Name = Path.GetFileName(filePath),
  Parent = new BoxRequestEntity() { Id = "0" }
  };

  BoxFile file = await client.FilesManager.UploadAsync(requestParams, fileStream);
  }
  ret = File.Exists(filePath);
  return ret;

  });
  task.Wait();
  return task.Result;

   

  This is the code in c#

  On task.Wait() it pops with error:
