Creating a byte array from a stream

Question

What is the prefered method for creating a byte array from an input stream?

Here is my current solution with .NET 3.5.

Stream s;
byte[] b;

using (

You can even make it fancier with extensions:

namespace Foo
{
    public static class Extensions
    {
        public static byte[] ToByteArray(this Stream stream)
        {
            using (stream)
            {
                using (MemoryStream memStream = new MemoryStream())
                {
                     stream.CopyTo(memStream);
                     return memStream.ToArray();
                }
            }
        }
    }
}

And then call it as a regular method:

byte[] arr = someStream.ToByteArray()
