azure - 使用GetBlockBlobReference()时如何避免字符隐藏？

Question

当我使用 Microsoft Azure 的云 block Blob 的方法 GetBlockBlobReference() 时，我发现它将一些字符(例如 # )转换为 %23。这不是我想要的。我怎样才能避免这种情况？代码段如下:

string pvtFileName = "pvt/" + fileName.Replace(StlFilePostfix, PvtFilePostfix);//the name contains #
            BlobRequestOptions bl = new BlobRequestOptions();
            bl.RetryPolicy = new LinearRetry(TimeSpan.FromSeconds(50), 6);
            CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
            var blobContainerPVT = blobClient.GetContainerReference(smodContainer.ToLower());
            blobContainerPVT.CreateIfNotExists();
            try
            {
                CloudBlockBlob pvtBlob = blobContainerPVT.GetBlockBlobReference(pvtFileName);
                using (var fileStream = File.OpenRead(fileFullPath.Replace(StlFilePostfix, PvtFilePostfix)))
                {
                    pvtBlob.UploadFromStream(fileStream, null, bl);
                }} catch (Exception e)
            {
                Trace.TraceInformation(e.Message);
            }

无论我是否使用 HttpUtility.UrlEncode() 格式化文件名，该方法都会将 # 转换为 %23

Blob 名称必须符合以下命名规则:

A blob name can contain any combination of characters.

A blob name must be at least one character long and cannot be more than 1,024 characters long.

Blob names are case-sensitive.

Reserved URL characters must be properly escaped.

The number of path segments comprising the blob name cannot exceed 254. A path segment is the string between consecutive delimiter characters (e.g., the forward slash '/') that corresponds to the name of a virtual directory.

URI 的区别仅在于是否为 reserved character is percent-encoded或 按字面意思出现的字符通常被认为是不等价的(表示相同的资源)，除非可以确定所讨论的保留字符没有保留目的。
