AIR打开本地文件

示例：
<?xml version="1.0" encoding="utf-8"?>
<mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
<mx:Script>
<![CDATA[
import mx.controls.Image;
   
    import flash.filesystem.*;
    import flash.events.Event;


private function click(e:MouseEvent):void
{
var fileForOpen:File=new File();

try
{
fileForOpen.browseForOpen("open");
fileForOpen.addEventListener(Event.SELECT,selectHandler);
}
catch (error:Error)
{
trace("Failed:"+error.message);
}
}

private function selectHandler(e:Event):void
{
var fileStream:FileStream=new FileStream();
fileStream.open(e.target as File,FileMode.READ);
var fileData:String=fileStream.readMultiByte(fileStream.bytesAvailable,"gb2312");
text.text=fileData;
}
]]>
</mx:Script>
<mx:Button id="open2" x="0" y="300" label="open" click="click(event)" />
<mx:TextArea id="text" width="200" height="300"/>
</mx:WindowedApplication>


但是存在一个问题，读取外部文档时，只能是.txt文档，而不能是.doc文档，doc文档会出现乱码，可能是编码方面的问题吧～～～～～
