Rackspace CloudFiles：检查文件是否存在

Question

I want to check for the existence of a file on the CDN through my site's code via the Rackspace Cloud API.

What would the best way to do this be? I am currently using the following:

... initialize API ... 

Dim containerItemList As List(Of String) = connection.GetContainerItemList("MyCDN") 

If containerItemList.Contains(MyFile) Then 
  'Blah blah 
End If 

This isn't working for some reason - the containerItemList is always empty. My container definitely has objects, and the name of the container is right (including case).

Is there a better/different way to search/check for the existence of a file? Ideally, it should be a case-insensitive search.

Another way would be to try and get the object using something like connection.GetStorageItem, and check for exceptions, but obviously that would hurt performance.

Any ideas? Code in any language would be fine, I'm just looking for the best way to do this.

Thanks in advance!
