wpf中，Panel里面的东西如果想保存到本地xaml文件怎么做？

另外保存后下次使用怎么调用？

参考技术A 保存
using (FileStream fs = new FileStream(
System.IO.Path.Combine(Environment.CurrentDirectory, "saved.xaml"),
FileMode.Create, FileAccess.Write))

XamlWriter.Save(mainCanvas, fs);//mainCanvas为你的Panel的Name
fs.Close();

读取
using (FileStream fs = new FileStream(
System.IO.Path.Combine(path, "saved.xaml"),//path为路径
FileMode.Open, FileAccess.Read))

Canvas newCanvas = (Canvas)XamlReader.Load(fs);
mainCanvas.Children.Clear();
for (int i = newCanvas.Children.Count - 1;i >= 0; --i)

UIElement el = newCanvas.Children[i];
newCanvas.Children.RemoveAt(i);
mainCanvas.Children.Add(el);

fs.Close();

主要用xmlwrite和xmlreader本回答被提问者采纳
