Question

Using this code:

    private async void writeToStorage(string contents)
    {
        var roamingFolder = Windows.Storage.ApplicationData.Current.RoamingFolder;
        var storFile = await roamingFolder.CreateFileAsync("test", CreationCollisionOption.ReplaceExisting);

        await Windows.Storage.FileIO.WriteTextAsync(storFile, contents);
    }

Do I need to close the file? And if so.. how do I do that? There is no Close on the storFile.

Answer 1

No you do not need to close this file.

StorageFolder and StorageFile instances are just a pointers to a folder and a file.
Using the WriteTextAsync method will open/write and close automatically the stream.
