我们来看这样一个例子：

复制代码 代码如下:

private function test() : void {

var canvas :Canvas = new Canvas();

canvas.width = 100;

canvas.height = 100;

// 保存到ByteArray

var b : ByteArray = new ByteArray();

b.writeObject(canvas);

// 取出对象

b.position = 0;

var o : Object = b.readObject();

var c : Canvas = objectToInstance(o,Canvas) as Canvas;

trace(c.width);

trace(c.height);

this.addChild(c);

}
