如何读取文件 (Metro/WinRT)

How to read file (Metro/WinRT)(如何读取文件 (Metro/WinRT))

问题描述

我对这个看似简单的任务的明显复杂性感到非常震惊.我知道我必须使用 StorageFile 类，并且我发现了这个 示例，但我只想读取一个我知道路径的文件，并将其数据作为文本读取到字符串中.

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.

从我收集到的资料来看，要使用 StorageFile 读取文件，我必须通过一堆接口；IAsyncOperation 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.

一定有更好(更简单)的方法.比如:

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

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

显然这不起作用，但也许我错过了什么，或者有人可以向我解释如何以不同的方式读取文件?

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?
