Azure blob download to stream有错误

Question

我正在尝试将Azure blob下载到MemoryStream，我收到错误“'memoryStream.ReadTimeout'引发了类型'System.InvalidOperationException'的异常”。但我可以下载到文件。

代码段位于

之下

private static void GetExcelBlobData(string filename, string connectionString, string containerName)
        {
            // Retrieve storage account from connection string.
            CloudStorageAccount storageAccount = CloudStorageAccount.Parse(connectionString);

            // Create the blob client.
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();

            // Retrieve reference to a previously created container.
            CloudBlobContainer container = blobClient.GetContainerReference(containerName);

            // Retrieve reference to a blob named "test.xlsx"
            CloudBlockBlob blockBlobReference = container.GetBlockBlobReference(filename);

            DataSet ds;
            using (var memoryStream = new MemoryStream())
            {
                //downloads blob's content to a stream
                blockBlobReference.DownloadToStream(memoryStream);
            }
        }

显示“blockBlobReference.DownloadToStream（memoryStream）”行上的调试控制台错误

有谁知道我在这里做错了什么？
