.Net SDK 云对象存储示例代码 下载对象，下载的文件未能正常关闭，异步回调死锁导致进程占用

[levi930]

// 初始化 TransferConfig TransferConfig transferConfig = new TransferConfig();

// 初始化 TransferManager TransferManager transferManager = new TransferManager(cosXml, transferConfig);

String bucket = "examplebucket-1250000000"; //存储桶，格式：BucketName-APPID String cosPath = "exampleobject"; //对象在存储桶中的位置标识符，即称对象键 string localDir = System.IO.Path.GetTempPath();//本地文件夹 string localFileName = "my-local-temp-file"; //指定本地保存的文件名

// 下载对象 COSXMLDownloadTask downloadTask = new COSXMLDownloadTask(bucket, cosPath, localDir, localFileName);

downloadTask.progressCallback = delegate (long completed, long total) { Console.WriteLine(String.Format("progress = {0:##.##}%", completed * 100.0 / total)); };

try { COSXML.Transfer.COSXMLDownloadTask.DownloadTaskResult result = await transferManager.DownloadAsync(downloadTask); Console.WriteLine(result.GetResultInfo()); string eTag = result.eTag; } catch (Exception e) { Console.WriteLine("CosException: " + e); }

代码运行完成后，下载的资源文件会被进程占用，排查回调死锁导致FileStream未关闭
