I received a rather...vague...error when trying out a bit of .NET code to connect to a Windows Azure Blob Storage account, and create a new container in which to store some blobs.
The code
CloudStorageAccount storageAccount = CloudStorageAccount.Parse(
"DefaultEndpointsProtocol=https;AccountName=REMOVED;AccountKey=REMOVED");
CloudBlobClient blobClient = storageAccount.CreateCloudBlobClient();
CloudBlobContainer container =
blobClient.GetContainerReference("TestContainer1");
container.CreateIfNotExist(); // This error'd
The error
A StorageClientException was thrown saying "One of the request inputs is out of range.". An inner WebException showed that "The remote server returned an error: (400) Bad Request."The cause
I'd assumed (incorrectly) that a container name could be pretty much any string. But that's not the case. As per this MSDN reference, a container name must:- be in lowercase (this was the cause in my case)
- start with a letter or a number and only contain letters, numbers and hyphens (multiple consecutive hyphens are not allowed)
- be between 3 and 63 characters long
