Question

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> and IAsyncOperationCompletedHandler.

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?

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;
}
