A System.Threading.Tasks containing a ResourceResponse<TResource> which wraps a Attachment containing the updated resource record.

Exceptions

ArgumentNullException

DocumentClientException

This exception can encapsulate many different types of errors. To determine the specific error always look at the StatusCode property. Some common codes you may get when creating a Document are:

StatusCode	Reason for exception
404	NotFound - This means the resource you tried to delete did not exist.

Examples

//Fetch the item to be updated
Attachment attachment = client.CreateAttachmentQuery(attachmentLink)
                            .Where(r => r.Id == "attachment id")
                            .AsEnumerable()
                            .SingleOrDefault();

//Update some properties on the found resource
attachment.MediaLink = "updated value";

//Now persist these changes to the database by replacing the original resource
Attachment updated = await client.ReplaceAttachmentAsync(attachment);
