楼主您好，我使用你的demo上传多媒体文件的时候总是报错，


        internal byte[] UploadMedia(string url, string method, string fileName)
        {
            if (!File.Exists(fileName))
                throw new FileNotFoundException("需要上传的文件不存在");
            var fileStream = new FileStream(fileName, FileMode.Open, FileAccess.Read);
            fileStream.Seek(0, SeekOrigin.Begin);
            var fileBuffer = new byte[fileStream.Length];
            fileStream.Read(fileBuffer, 0, fileBuffer.Length);
            fileStream.Dispose();
            var boundary = GenerateRadomStr();
            this.Headers["Content-Type"] = string.Format("multipart/form-data; boundary={0}", boundary);
            string fileFormdataTemplate =
                            "\r\n--" + boundary +
                            "\r\nContent-Disposition:form-data;name=\"{0}\";filename=\"{1}\"" +
                            "\r\nContent-Type:application/octet-stream" +
                            "\r\n\r\n";
            string formDataHeader = String.Format(fileFormdataTemplate, "media", fileName);
            byte[] formDataHeaderBuffer = Encoding.UTF8.GetBytes(formDataHeader);


            string begin = $"--{boundary}\r\n";
            byte[] beginBuffer = Encoding.UTF8.GetBytes(begin);


            string end = $"\r\n--{boundary}--\r\n";
            byte[] endBuffer = Encoding.UTF8.GetBytes(end); ;


            byte[] dataStream = new byte[formDataHeaderBuffer.Length + beginBuffer.Length + fileBuffer.Length + endBuffer.Length];
            formDataHeaderBuffer.CopyTo(dataStream, 0);
            beginBuffer.CopyTo(dataStream, formDataHeaderBuffer.Length);
            fileBuffer.CopyTo(dataStream, formDataHeaderBuffer.Length + begin.Length);
            endBuffer.CopyTo(dataStream, formDataHeaderBuffer.Length + begin.Length + fileBuffer.Length);
            //var returnBuffer = await this.UploadDataTaskAsync(url, "POST", dataStream);
            var returnBuffer = this.UploadData(url, "POST", dataStream);
            return returnBuffer;
        }


提示我上传的多媒体类型错误
