I have been fighting with this upload problem for a couple of days and searched the forum for a good answer but have not seen it yet. I am using asp.net and I am currently receiving a timeout when I try to post a file to upload. I have taken the MultipartWebRequest class from the V1 C# Api and changed it(i believe to be correctly but it may be my problem) to work with my program.
public sealed class MultipartWebRequest
{
public string AcceptCharset { get; set; }
public string AcceptEncoding { get; set; }
public string Url { get; set; }
public string Boundary { get; set; }
public string ApiKey { get; private set; }
public string Token { get; private set; }
public MultipartWebRequest(string apiKey, string token, string submitUrl,string acceptCharset = "ISO-8859-1", string acceptEncoding = "gzip,deflate" )
{
Boundary = "----------------" + DateTime.Now.Ticks;
ApiKey = apiKey;
Token = token;
Url = submitUrl;
AcceptCharset = acceptCharset;
AcceptEncoding = acceptEncoding;
}
public string SubmitFiles(
//string[] filePaths,
UploadableFile[] files,
bool isShared,
string message,
string[] emailsToNotify,
string folderId)
{
byte[] buffer;
using (MemoryStream resultStream = new MemoryStream())
{
if (files != null)
{
buffer = AssembleFilesBlock(files, folderId);
resultStream.Write(buffer, 0, buffer.Length);
}
if (!string.IsNullOrEmpty(message))
{
buffer = AssembleMessageBlock(message);
resultStream.Write(buffer, 0, buffer.Length);
}
//buffer = AssembleSharedBlock(isShared);
//resultStream.Write(buffer, 0, buffer.Length);
if (emailsToNotify != null)
{
buffer = AssembleEmailsBlock(emailsToNotify);
resultStream.Write(buffer, 0, buffer.Length);
}
buffer = GetFormattedBoundary(true);
resultStream.Write(buffer, 0, buffer.Length);
resultStream.Flush();
buffer = resultStream.ToArray();
}
HttpWebRequest myRequest = CreateRequest(buffer.Length);
using (Stream stream = myRequest.GetRequestStream())
{
stream.Write(buffer, 0, buffer.Length);
stream.Close();
}
string response;
using (HttpWebResponse myHttpWebResponse = (HttpWebResponse)myRequest.GetResponse())
using (Stream responseStream = myHttpWebResponse.GetResponseStream())
{
StreamReader reader = new StreamReader(responseStream);
response = reader.ReadToEnd();
responseStream.Close();
}
myHttpWebResponse.Close();
return response;
}

As you can see I have tried all of the different upload urls that I have found around the site. And with all the different ones, not sure exactly which one to use, but doc appears to be the latest “most” correct one? Any help with this would be greatly appreciated as I am fairly new (but understand) to post requests in C#, but VERY new (never done one) to multipart forms in C# (or really anywhere).
The current recommended URL for the API (including file uploads) appears to now be https://api.box.com/2.0. Have you tried using that base URL?
