How to read file (Metro/WinRT)
Solution 1
This web page might be helpful: http://blog.jerrynixon.com/2012/06/windows-8-how-to-read-files-in-winrt.html
Relevant code:
public string CurrentFileBuffer
{
get; private set;
}
public async void ReadTextFile(string Path)
{
var folder = Package.Current.InstalledLocation;
var file = await folder.GetFileAsync(Path);
var read = await FileIO.ReadTextAsync(file);
CurrentFileBuffer = read;
}
Solution 2
Windows.Storage.FileIO has a bunch of helper/utility methods that do the job in a single line of code rather than using StorageIO interfaces and classes.
e.g.
ReadLineAsync()
ReadTextAsync()
WriteLineAsync()
WriteTextAsync()
Solution 3
You can get your file by using this:
StorageFile file3 = await StorageFile.GetFileFromPathAsync(@"C:\myFile.txt");
annonymously
I could be over 50 years old, or I couldn't. I could be 3 feet tall, or I couldn't. I could eat raw coffee beans, or I couldn't. I could have a pet elephant, and you wouldn't know it. That is the nature of annonimity. Spelled with double 'n' first instead of second. Yeah.

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.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>
andIAsyncOperationCompletedHandler
.There must be a better (simpler) way. Something like:
using (StorageFile sf = StorageFile.OpenAsync("myFile.txt")) { string line = sf.ReadLine(); }
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?

annonymously over 11 yearsThanks, finally someone actually read my question. This was giving me a really hard time. If you'd be so inclined, you could copy some of the code from that link to help future visitors.

Matthew Watson over 11 yearsI would, but bizarrely, the code is in a bitmap rather than selectable text. :(
