MemoryLeak: MemoryStream not freed up after uploading

[fengyuan213]

Hi Dev,
Recently I am using .net 5 to make an upload queue using Qcloud, When finished proceeding with uploading, the memory stream associated with it has not been properly released which takes a quite a large amount of memory.

Code to upload for a single file

void Wait(){
            CurrentUploadingTask.Wait();
}
void Start(){
         // 初始化 TransferConfig
            var transferConfig = new TransferConfig();
            // 初始化 TransferManager
            var transferManager = new TransferManager(CosXml, transferConfig);
            
            // 存储桶名称，此处填入格式必须为 bucketname-APPID, 其中 APPID 获取参考 https://console.cloud.tencent.com/developer

            var bucket = TencentBucketAppId;
            var cosPath = UploadPackage.ResourceKey; //对象在存储桶中的位置标识符，即称对象键
            var srcPath = UploadPackage.FileLocalPath; //本地文件绝对路径

            // 上传对象
            var uploadTask = new COSXMLUploadTask(bucket, cosPath);

            uploadTask.SetSrcPath(srcPath);
            uploadTask.failCallback = FailCallback;
            uploadTask.successCallback = UploadSucceedCallBack;
            uploadTask.progressCallback = UploadProgressCallBack;
            
            CosXmlUploadTask = uploadTask;
            CurrentUploadingTask = transferManager.UploadAsync(uploadTask);
       
}
