Flex 输出文件到本地的两种方法

在flex中输出文件到本地目前我用到两种方法，分别是File和FielRefreence

例子：

var exportString:String = "这就是一个测试"

1、File输出

var ff:File = File.desktopDirectory.resolvePath("Progress.CSV");

ff.addEventListener(Event.SELECT,exportCSVSelectedHandler);

ff.browseForSave("选择路径");



private function exportCSVSelectedHandler(event:Event):void

{

var dir:String = event.target.nativePath;

var writeStream:FileStream = new FileStream();

writeStream.open(new File(dir),FileMode.WRITE);

var content:String = "jhfdklahflaksjdhflkasjhflaskjhlf\n";

writeStream.writeMultiByte(content,'utf-8');

writeStream.close();

}

var content:String = "jhfdklahflaksjdhflkasjhflaskjhlf\n";



var f:FileReference = new FileReference();

f.save(content,"1.csv");
