问题描述

有一个构造函数用于指定文件路径。然而，在对象Broswer和放大器;在元数据不存在

There is a constructor for specifying a file path. Yet in Object Broswer & in the meta data it does not exist.

And apparently all .NET for Metro things are referenced in the References Tab.

我只是试图从项目文件夹，仅此而已访问一个txt文件。如果任何人有一个替代我所有的耳朵。

I am simply trying to access a txt file from the Project Folder, nothing more. If anyone has an alternative I am all ears.

推荐答案

这是在WinRT中的根本性变化之一。你不能只写一个文件，任何你想要的了，你必须使用独立存储。而你需要使用异步I / O与等待的关键字。

"This is one of the fundamental changes in WinRT. You can't just write a file anywhere you want anymore, you have to use isolated storage. And you need to use asynchronous I/O with the await keyword."
