将图像保存在applicationStorageDirectory中的目录中

Question

我试图将图像文件保存到我的air项目的applicationStorageDirectory中的目录中。首先创建目录

 var imageDirectory:File = File.applicationStorageDirectory.resolvePath("vispics");

   if (imageDirectory.exists)
   {
       Alert.show("Directory Already Exists");

   }
   else {
       imageDirectory.createDirectory();
       Alert.show(imageDirectory.nativePath);
   }

下一部分是从我的摄像头保存图像，现在它保存到applicationStorageDirectory。我是怎么做的

     var randInt:int = Math.random() * (99999 - 1001) + 1001;
      var randStr:String = randInt.toString();
      var filename:String = ""+randStr+".jpg";


        var file:File = File.applicationStorageDirectory.resolvePath( filename );
        var wr:File = new File( file.nativePath );
    var stream:FileStream = new FileStream();
        stream.open( wr , FileMode.WRITE);
        stream.writeBytes ( imageData, 0,imageData.length );
        stream.close();

有没有办法可以将图像存储在我的“vispics”目录中？ 提前谢谢。

尝试：

var file:File = File.applicationStorageDirectory.resolvePath("vispics/" + filename);
