JSON/XML序列化与反序列化(非构造自定义类)

隔了很长时间再重看自己的代码,觉得好陌生。。以后要养成多注释的好习惯。。直接贴代码。。对不起( ▼-▼ )

保存保存:进行序列化后存入应用设置里

ApplicationDataContainer _appSettings = ApplicationData.Current.LocalSettings;  //这个是保存一些页面输入信息private async void Save_Click(object sender, RoutedEventArgs e)        {            if (userName.Text == "" || userAge.Text == "")            {                await new MessageDialog("请输入完整的信息").ShowAsync();                return;            }            ObservableCollection<School> education = new ObservableCollection<School>();            if (school1.IsChecked == true)                education.Add(new School() { Id = "id001", Name = school1.Content.ToString() });            if (school2.IsChecked == true)            {                education.Add(new School() { Id = "id002", Name = school2.Content.ToString() });            }            User user = new User()            {                Education = education,                Id = Guid.NewGuid().ToString(),//随机生成   前面用到过的                Name = userName.Text,                Age = Int32.Parse(userAge.Text),                Verified = false               };             //使用DataContractJsonDeSeriaLizer实现方式            string json = ToJsonData(user);  //带参数的构造函数            //string json = user.Stringify();//这个是构造自定义的类的,此处用不到            info.Text = json;            _appSettings.Values["UserDataKey"] = json; //存放到应用设置里面            await new MessageDialog("保存成功").ShowAsync();        }

获取数据:从应用设置取出,进行反序列化取出信息

private async void Get_Click(object sender, RoutedEventArgs e)        {            if (!_appSettings.Values.ContainsKey("UserDataKey"))            {                await new MessageDialog("未保存信息").ShowAsync();                return;            }            string json = _appSettings.Values[UserDataKey].ToString();            //反序列化为实体类对象            User user = DataContractJsonSerializer<User>(json);            //User user = new User(json);            string userInfo = "";            userInfo = "Id:" + user.Id + "Name:" + user.Name + "Age:" + user.Age;            foreach (School school in user.Education)            {                userInfo += "Education:" + "Id:" + school.Id + "name:" + school.Name;            }            await new MessageDialog(userInfo).ShowAsync();        }private T DataContractJsonSerializer<T>(string jsonString)        {            var ds = new DataContractJsonSerializer(typeof(T));            var ms = new MemoryStream(Encoding.UTF8.GetBytes(jsonString));            T obj = (T)ds.ReadObject(ms);            ms.Dispose();            return obj;        }

不贴了。。看的好难受。。以后再也不会这么敷衍了。大家多看看其他的也行。

 

收获:

ObservableCollection<>相对List<>来说,绑定到ListBox会自动刷新

也就是当你在进行增加、删除操作时,前台会动态的显示。

 

有需要源码(WP8.1)的可以下载。包含了JSON/Xml的两种(构造与不构造类)操作方式。。
