public void FinishUpload(string username, string password, int uploadId, long expectedLength)
This method must only be called after all the required data has been uploaded. The expectedLength parameter must
be set to the number of bytes the client has uploaded for this file using the
UploadBlock method in order to allow the service to validate that it
has received the expected amount of data before the client submits the data for cleansing.
Note that, once this method has been called, no more data can be uploaded using the UploadBlock method.
In addition, the SubmitJob method cannot be called until after this method.
