I'm developing a Windows Phone 8.1 app and I have to check some informations before executing some methods (I have to check if the internet connection is available and if the localization is active). 我正在开发Windows Phone 8.1应用程序，必须在执行某些方法之前检查一些信息（我必须检查Internet连接是否可用以及本地化是否处于活动状态）。 There are interceptors or another way to programmatically execute a method before some actions in wp8.1? 在wp8.1中执行某些操作之前，是否有拦截器或其他方法可以以编程方式执行方法？

The .NET platform has something called Code Contracts. .NET平台有一个称为代码合同的代码。 Basically, starting from .NET 4.0, you can use Contract.Requires(Boolean) to verify if a precondition is active. 基本上，从.NET 4.0开始，可以使用Contract.Requires(Boolean)来验证前提条件是否处于活动状态。 You can even show a special message to the user when it's not active. 您甚至可以在不活动时向用户显示一条特殊消息。
