Cannot send a content-body with this verb-type. error while getting response when trying to Upload file in Box Storage - winforms

Question

When i am trying to upload files in Box Storage using api provided by Box but at response time i am getting this error
public static void UploadFileRequest(string FolderID, string accesstoken)
{
string boundary = string.Format("----------------------------{0}", DateTime.Now.Ticks.ToString("x"));
string filename="C:\\Users\\Administrator\\Desktop\\Text.txt";
HttpWebRequest httpWReq = (HttpWebRequest)WebRequest.Create("https://upload.box.com/api/2.0/files/content");
ASCIIEncoding encoding = new ASCIIEncoding();
string hh = "\"filename=#\"" + filename + "\" "+";"+"";
hh += "parent_id=\"" + FolderID + "\"";
string kj = string.Format(("filename=#" + filename));
byte[] data = encoding.GetBytes(hh);
httpWReq.Headers.Add("Authorization", "Bearer " + accesstoken);
httpWReq.ContentType = "application/json";
httpWReq.ContentLength = data.Length;
using (Stream stream = httpWReq.GetRequestStream())
{
stream.Write(data, 0, data.Length);
}
HttpWebResponse response = (HttpWebResponse)httpWReq.GetResponse();
string responseString = new StreamReader(response.GetResponseStream()).ReadToEnd();
}

Answer 1

Without knowing the Box API, I will assume that the upload should be a POST operation, so you will need to specify the correct HTTP method on your request, before sending it:
httpWReq.Method = "POST";
The Method property defaults to "GET", and GET operations does not normally have a body..

Answer 2

Here is the solution , as C# accepts bytes format and then any Upload is done , i was missing that .. hope it helps
private void UploadBoxFile(string Filename)
{
HttpWebRequest req = HttpWebRequest.Create("https://upload.box.com/api/2.0/files/content") as HttpWebRequest;
req.Method = "POST";
req.Headers.Add("Authorization", "Bearer < Access Token >");
req.ContentType = "multipart/form-data; boundary=\"d174f29b-6def-47db-8519-3da38b21b398\"";
string Content = GetFormatedData(Filename);
req.ContentLength = Content.Length;
using (Stream Writer = req.GetRequestStream())
{
Writer.Write(Encoding.UTF8.GetBytes(Content), 0, Content.Length);
}
req.GetResponse();
}
private string GetFormatedData(string Filename)
{
StringBuilder build = new StringBuilder();
string Id = "d174f29b-6def-47db-8519-3da38b21b398";
build.AppendLine("--" + Id);
build.AppendLine("Content-Disposition: form-data; filename=\"hello1.txt\"; name=\"filename\"");
build.AppendLine("Content-Type: application/octet-stream");
build.AppendLine();
string FileContent = "This is a sample text";
build.AppendLine(FileContent);
build.AppendLine("--" + Id);
build.AppendLine("Content-Disposition: form-data; name=\"folder_id\"");
build.AppendLine();
build.AppendLine("0");
build.AppendLine("--" + Id + "--");
return build.ToString();
}
Thanks..
