如何读取文件（城域/ WinRT的） [英] How to read file (Metro/WinRT)

问题描述

我对这个看似简单的任务明显的复杂性相当震惊。我知道我必须使用 StorageFile 类，我发现这个的example ，但我只是想读一个单一的文件，而我知道路径，阅读它的数据作为文本字符串。

I'm quite astounded by the apparent complexity of this seemingly simple task. I know that I have to use the StorageFile class, and I've found this example, but I just want to read one single file, to which I know the path, and read it's data as text into a string.

从我已经能够收集，阅读与 StorageFile 的文件，我必须要经过一堆接口; IAsyncOperation< StorageFile方式> 和 IAsyncOperationCompletedHandler

From what I've been able to gather, to read a file with StorageFile, I have to go through a bunch of interfaces; IAsyncOperation<StorageFile> and IAsyncOperationCompletedHandler.

有一定是一个更好的（简单）的方式。是这样的：

There must be a better (simpler) way. Something like:

using (StorageFile sf = StorageFile.OpenAsync("myFile.txt"))
{
    string line = sf.ReadLine();
}

显然，这并不工作，但也许我错过了什么，或？有人能向我解释如何阅读方式不同的文件

Obviously this doesn't work, but maybe I've missed something, or someone could explain to me how to read a file in a different way?
