Updated: April 24, 2013

[This topic is part of the Windows Azure Storage Client Library 1.7, which has been deprecated. The current recommended version is Storage Client Library 3.0.]

Gets the blob's system properties.

Namespace: Microsoft.WindowsAzure.StorageClient
Assembly: Microsoft.WindowsAzure.StorageClient (in Microsoft.WindowsAzure.StorageClient.dll)

'Usage

public:
property BlobProperties^ Properties {
	BlobProperties^ get ();
}

Property Value

The blob's properties.

The following code example lists blob properties and metadata.

static void ListBlobPropertiesAndMetadata(Uri blobEndpoint, string accountName, string accountKey)
{
    //Create service client for credentialed access to the Blob service.
    CloudBlobClient blobClient = new CloudBlobClient(blobEndpoint, new StorageCredentialsAccountAndKey(accountName, accountKey));

    //Get a reference to a blob.
    CloudBlob blob = blobClient.GetBlobReference("mycontainer/myblob.txt");

    //Populate the blob's attributes.
    blob.FetchAttributes();

    //List some blob properties.
    Console.WriteLine("Blob: " + blob.Attributes.Uri);
    Console.WriteLine();

    Console.WriteLine("Blob properties:");
    Console.WriteLine("\tBlobType: " + blob.Attributes.Properties.BlobType);
    Console.WriteLine("\tLastModifiedUTC: " + blob.Attributes.Properties.LastModifiedUtc);
    Console.WriteLine("\tETag: " + blob.Attributes.Properties.ETag);
    Console.WriteLine();

    //Enumerate the blob's metadata.
    foreach (var metadataKey in blob.Metadata.Keys)
    {
        Console.WriteLine("Metadata name: " + metadataKey.ToString());
        Console.WriteLine("Metadata value: " + blob.Metadata.Get(metadataKey.ToString()));
    }
}


Returning a reference to a blob does not automatically provide access to the blob's properties, because it does not necessarily involve a request to the service. To populate a blob's properties, call the FetchAttributes method or the BeginFetchAttributes and EndFetchAttributes methods. Calling these methods before reading a blob's properties will ensure that the property values are up-to-date.
