#creat CloudBlobClient 
Add-Type -Path "C:\Program Files\Microsoft SDKs\Windows Azure\.NET SDK\v2.3\ref\Microsoft.WindowsAzure.StorageClient.dll" 
$storageCredentials = New-Object Microsoft.WindowsAzure.StorageCredentialsAccountAndKey -ArgumentList $StorageName,$StorageKey 
$blobClient =   New-Object Microsoft.WindowsAzure.StorageClient.CloudBlobClient($BlobUri,$storageCredentials) 
#set Properties and Metadata 
$cacheControlValue = "public, max-age=60480" 
foreach ($blob in $blobs) 
{ 
  #set Metadata 
  $blobRef = $blobClient.GetBlobReference($blob.Name) 
  $blobRef.Metadata.Add("abcd","abcd") 
  $blobRef.SetMetadata() 

  #set Properties 
  $blobRef.Properties.CacheControl = $cacheControlValue 
  $blobRef.SetProperties() 
}
