inkCanvas 怎么把其上面的控件（主要是视频和图片）和墨迹一样保存起来，下次能再一次打开进行编辑涂鸦

你好，

1. 首先我们需要了解序列化和反序列化：

2. 墨迹之类的肯定是一个个的对象或者对象集合，那我们可以根据自己程序的逻辑把他们序列化保存到文件中，下次打开时先加载上一次保存的文件，然后反序列化它。这样就可以在界面上显示原先的墨迹了。

或者把当前的Canvas上面的内容保存为XAML文件，下次再打开。

public static void SerializeToXML(MainWindow window, Canvas canvas, int dpi, string filename) { string mystrXAML = XamlWriter.Save(canvas); FileStream filestream = File.Create(filename); StreamWriter streamwriter = new StreamWriter(filestream); streamwriter.Write(mystrXAML); streamwriter.Close(); filestream.Close(); }
