Flex 取得文本(txt)内容，并且输出是汉字

private function GetFile():void{       

           var getFileContent:FileStream = new FileStream();          

           var directory:File = new File(filePath);

           var tempPath:String = new String();

           if (directory != null)

           {

           getFileContent.open(directory, FileMode.READ);

  var getContent:String = getFileContent.readMultiByte(getFileContent.bytesAvailable,"gb2312");  

  var tempStr:String = "Share=";

  var getString:String = "";

  var getPath:String = "";

 

  for (var j:int = 0;j<2;j++)

  {

  getString = getContent.substring(getContent.indexOf(tempStr));  

  getPath = getString.substring(0,getString.indexOf("/n"));

  getPath=getPath.substring(0,getPath.lastIndexOf("/r"));

  getPath = getPath.substring(6);

  if (getPath != "")

  break;

  else

  tempStr = "share=";

  }

  if (getPath == "" && j == 2)

  {

  myTimer.stop();

  Alert.yesLabel= "是";

Alert.show("目录或文件不存在！请检查C://WINDOWS//abc.ini下“Share=”的路径，并且设置“share=”为“share=”或“Share=”","提示",Alert.YES,this,doAlertExit);

return;

  }

 

  tempPath = getPath + "/DATA";

  tempPath = tempPath.replace(////g,"////");

 

  var dir:File = new File(tempPath);

 

var contents:Array = dir.getDirectoryListing(); 

var isExist:Boolean = false;

 

 

for (var i:uint = 0; i < contents.length; i++) 

{

   directory = directory.resolvePath(contents[i].name);  // name of file to read

 

if (contents[i].name == "eBoard.txt")

{

isExist = true;

break;

}

}

if (isExist == true)

{

getPath += "/DATA//eBoard.txt";

  getPath = getPath.replace(////g,"////");

  var file:File = new File(getPath);

  var inStream:FileStream = new FileStream();  

  inStream.open(file, FileMode.READ);

  txt.text = inStream.readMultiByte(inStream.bytesAvailable,"gb2312");  //这里为转化成汉字的格式，如果txt的字符编码为UTF-8，则这里就修改readUTF，现在这里的txt是ASCII码

  inStream.close();

}

else

{

Alert.yesLabel= "是";

Alert.show("目录或文件不存在！请在" + tempPath + "下建立文件eBoard.txt","提示",Alert.YES,this,doAlertExit);

}

 

  getFileContent.close(); 

           }

     

        }

 

以上代码是，找到固定盘符下某个文件，读其内容中的某一部分，这部分内容为一个文件路径，再找到这个文件，读其内容，包含了文件读取，字符串匹配，等内容

写文件：

 

 

private function outFile(fileName:String, data:ByteArray):void

{

    var outFile:File = File.desktopDirectory; // dest folder is desktop

    outFile = outFile.resolvePath(fileName);  // name of file to write

    var outStream:FileStream = new FileStream();

    // open output file stream in WRITE mode

    outStream.open(outFile, FileMode.WRITE);

    // write out the file

    outStream.writeBytes(data, 0, data.length);

    // close it

    outStream.close();
