Does the .net framework provides async methods for working with the file-system?

Question

Does the .net framework has an async built-in library/assembly which allows to work with the file system (e.g. File.ReadAllBytes, File.WriteA

Answer 1

If you have to write a file in a background task you can write it sincronously in an async method.

static void Main(string[] args)
{
    Console.WriteLine("1");
    // thread 1, sync
    byte[] dataToWrite = System.Text.ASCIIEncoding.ASCII.GetBytes("my custom data");
    Task.Run(() =>
    {
        Console.WriteLine("2");
        // aspetto un secondo
        System.Threading.Thread.Sleep(1000);
        // thread 2, async code
        System.IO.File.WriteAllBytes(@"c:\temp\prova.txt", dataToWrite);
        Console.WriteLine("2, end");
    });

    Console.WriteLine("3, exit");

    Console.ReadLine();
    // thread 1
}

the execution output will be: 1,3,2,2 end
