将文件上传到Azure Blob存储中

Question

我正在尝试使用以下代码上传存储在MemoryStream中的文件。

        private static void SaveStream(MemoryStream stream, string fileName)
        {
            var blobStorageService = new BlobStorageService();
            UploadBlob(stream, fileName);
        }

        public void UploadBlob(MemoryStream fileStream,string fileName)
        {
            var blobContainer = _blobServiceClient.GetBlobContainerClient(Environment
                               .GetEnvironmentVariable("ContainerName"));
            var blobClient = blobContainer.GetBlobClient(fileName);
            blobClient.Upload(fileStream);  <--- Error Message

        }

错误消息：System.ArgumentException：'content.Position必须小于content.Length。请设置content.Position为要上传的数据的开头。'

Answer 1

发生这种情况是因为当前位置在流的末尾。您可以在上传之前将位置设置为流的开头

var blobClient = blobContainer.GetBlobClient(fileName);
fileStream.Position =0;
blobClient.Upload(fileStream)
