How do I save a stream to a file in C#?

Question

I have a StreamReader object that I initialized with a stream, now I want to save this stream to disk (the stream may be a .gif or .jpg

Answer 1

Another option is to get the stream to a byte[] and use File.WriteAllBytes. This should do:

using (var stream = new MemoryStream())
{
    input.CopyTo(stream);
    File.WriteAllBytes(file, stream.ToArray());
}

Wrapping it in an extension method gives it better naming:

public void WriteTo(this Stream input, string file)
{
    //your fav write method:

    using (var stream = File.Create(file))
    {
        input.CopyTo(stream);
    }

    //or

    using (var stream = new MemoryStream())
    {
        input.CopyTo(stream);
        File.WriteAllBytes(file, stream.ToArray());
    }

    //whatever that fits.
}
