ReNET上传文件有线程限制？？ 发下主要代码，请大家帮忙看下原因，谢谢。。。                 ObjectMetadata metadata = new ObjectMetadata();                 metadata.ContentType = 'application/file';                 ClientConfiguration config = new ClientConfiguration();                 config.ConnectionTimeout = -1;                  OssClient ossClient = new OssClient(new Uri('http://oss.aliyuncs.com'), AccessID, AccessKey, config);                 //单文件上传                 //fs = File.Open(FileToUpload, FileMode.Open);                 //PutObjectResult Result = ossClient.PutObject(Bucket, Key, fs, metadata);                 InitiateMultipartUploadRequest initRequest = new InitiateMultipartUploadRequest(Bucket, Key);                 InitiateMultipartUploadResult initResult = ossClient.InitiateMultipartUpload(initRequest);                 // 设置每块大小                 int partSize = 1024 * 1024 * 3;                 FileInfo partFile = new FileInfo(FileToUpload);                 FileSize = partFile.Length;                 // 计算分块数目                 int partCount = (int)(partFile.Length / partSize);                 if (partFile.Length % partSize != 0)                 {                     partCount++;                 }                 for (int i = 0; i                 {                     // 获取文件流                     FileStream fis = new FileStream(partFile.FullName, FileMode.Open,FileAccess.Read);                                          // 跳到每个分块的开头                     long skipBytes = partSize * i;                     fis.Position = skipBytes;                     // 计算每个分块的大小                     long size = partSize                             partSize : partFile.Length - skipBytes;                     // 创建UploadPartRequest，上传分块                     UploadPartRequest uploadPartRequest = new UploadPartRequest(Bucket, Key, initResult.UploadId);                     uploadPartRequest.InputStream = fis;                     uploadPartRequest.PartSize = size;                     uploadPartRequest.PartNumber = (i + 1);                     BackgroundWorker bw = new BackgroundWorker();                     bw.WorkerReportsProgress = true;                     bw.DoWork += new DoWorkEventHandler(bw_DoWork);                     bw.RunWorkerCompleted += new RunWorkerCompletedEventHandler(bw_RunWorkerCompleted);                     bw.RunWorkerAsync(new object[] { ossClient, uploadPartRequest, partCount, fis, i + 1 });                     Thread.Sleep(500);         //线程工作         void bw_DoWork(object sender, DoWorkEventArgs e)         {             object[] args = e.Argument as object[];             OssClient ossClient = args[0] as OssClient;             UploadPartRequest uploadPartRequest = args[1] as UploadPartRequest;             int partCount = int.Parse(args[2].ToString());             FileStream fis = args[3] as FileStream;             int partNumber = int.Parse(args[4].ToString());             long startPosition = fis.Position;             //实例化watcher对象，用于监视进度、速度、剩余时间，并加入列表             UploadWatcher watcher = new UploadWatcher() { partNumber = partNumber, startPosition = startPosition, uploadPosition=startPosition, fis = fis };             itemList.Add(watcher);             UploadPartResult uploadPartResult = ossClient.UploadPart(uploadPartRequest);               partETags.Add(uploadPartResult.PartETag);             threadDoneCount += 1;             e.Result = new object[] { ossClient, uploadPartRequest.UploadId, partCount };             UploadSize += ((long)uploadPartRequest.PartSize);         }         //线程完成         void bw_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)         {             object[] args = e.Result as object[];             OssClient ossClient = args[0] as OssClient;             string UploadId = args[1] as string;             int partCount = int.Parse(args[2].ToString());             //当最后一个线程执行完毕时，进行分块文件的合并             if (threadDoneCount == partCount)             {                 CompleteMultipartUploadRequest completeReq = new CompleteMultipartUploadRequest(Bucket, Key, UploadId);                 //对分块上传的返回信息按PartNumber排序，因为合并时要求必须是升序                 var query = from q in partETags                             orderby q.PartNumber ascending                             select q;                 List sortedPartETags = query.ToList();                 foreach (PartETag partETag in sortedPartETags)                 {                     completeReq.PartETags.Add(partETag);                 }                 CompleteMultipartUploadResult completeResult = ossClient.CompleteMultipartUpload(completeReq);                 UploadFilish = true;                 UploadOK = true;                 State = UploadState.done;             }         } ------------------------- ReNET上传文件有线程限制？？ 呃，解决了。SDK没有问题，是忘记设置.net的HttpRequest并发限制了，xp、win7默认限制都是2个。。。
