<t>This should work:<br/>
<br/>
var storageAccount = CloudStorageAccount.Parse("YOURCONNECTIONSTRING");<br/>
var blobClient = storageAccount.CreateCloudBlobClient();<br/>
<br/>
var blobs = blobClient<br/>
.GetContainerReference("thecontainer")<br/>
.ListBlobs(useFlatBlobListing: true)<br/>
.OfType();<br/>
<br/>
foreach (var blob in blobs)<br/>
{<br/>
if (Path.GetExtension(blob.Uri.AbsoluteUri) == ".mp4")<br/>
{<br/>
blob.Properties.ContentType = "video/mp4";<br/>
}<br/>
// repeat ad nauseam<br/>
blob.SetProperties();<br/>
}<br/>
<br/>
```<br/>
<br/>
Or set up a dictionary so you don't have to write a bunch of if statements.</t>
