Catel可以让你更方便的配置所有的平台
下面的表格解释了每个平台使用何种技术来获取和存储配置值。
| 平台 | 技术 |
| .NET | ConfigurationManager.AppSettings |
| Sliverlight | IsolatedStorageSettings.ApplicationSettings |
| WinRT | ApplicationData.Current.LocalSettings |
| PCL | 不支持 |
使用如下代码从配置中获取值：
var configurationService = new ConfigurationService(); var mySetting = configurationService.GetValue<int>("mySetting", 42);
注意：
It‘s best to retrieve the service from the dependency resolver or let it be injected into the classes using it
使用如下的代码存储值到配置中：
var configurationService = new ConfigurationService(); configurationService.SetValue("mySetting", 42);
注意：
It‘s best to retrieve the service from the dependency resolver or let it be injected into the classes using it
ConfigurationService是用于扩展的，尽管他默认的是.NET的本地存储系统，它很容易的去创建自定义服务，下面是一个创建自定义服务来存储或者读取数据库的例子。
public class DbConfigurationService : ConfigurationService { protected override bool ValueExists(string key) { using (var context = new ConfigurationContext()) { return (from config in context.Configurations where config.Key == key select config).Any(); } } protected override string GetValueFromStore(string key) { using (var context = new ConfigurationContext()) { return (from config in context.Configurations where config.Key == key select config.Value).First(); } } protected override void SetValueToStore(string key, string value) { using (var context = new ConfigurationContext()) { var configuration (from config in context.Configurations where config.Key == key select config).FirstOrDefault(); if (configuration == null) { configuration = context.CreateObject<Configuration>(); configuration.Key = key; } configuration.Value = value; context.SaveChanges(); } } }
不要忘记在ServiceLocator中注册自定义的ConfigurationService.
