I have used following code and worked fine for me ....and it will work when flash player 10 is installed and settings are changed as per below site:

SQL

FileRef.addEventListener(Event.SELECT,FileSelect);
    FileRef.addEventListener(Event.COMPLETE,onFileComplete);

C#

var filedata:ByteArray=new ByteArray();
        public function onFileComplete(event : Event) : void
             {
                         FileRef = event.currentTarget as FileReference;
                         filedata=FileRef.data;
                         var data:ByteArray = new ByteArray();
                         FileRef.data.readBytes(data,0,FileRef.data.length);
                                                       //  byteCheckUpload.writeLocation(data, FileRef.name)
                                                              }

C#

private function FileSelect(evt:Event):void
   {
         FileRef.load();
         Txt_FileName.text=evt.currentTarget.name;
    }

I think you can do something like this to fetch the byte array

XML

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" creationComplete="loadFile()">

    <mx:Script>
        <![CDATA[

                private var loadedFile:ByteArray;

                private function loadFile():void
                {
                        var request:URLRequest = new URLRequest("http://test.enunciato.org/sample.pdf");
                        var urlLoader:URLLoader = new URLLoader(request);

                        urlLoader.addEventListener(Event.COMPLETE, onURLLoaderComplete);
                        urlLoader.dataFormat = URLLoaderDataFormat.BINARY;
                        urlLoader.load(request);
                }

                private function onURLLoaderComplete(event:Event):void
                {
                        loadedFile = event.target.data;
                }

                private function saveLoadedFile():void
                {
                        var file:FileReference = new FileReference();
                        file.save(loadedFile, "SampleDoc.PDF");
                }

        ]]>
    </mx:Script>

    <mx:Button label="Save Image" horizontalCenter="0" verticalCenter="0" click="saveLoadedFile()" />

</mx:Application>
